Find the following functions on your calculatorWhile the bulk of the most common functions will have their own keys e.g., the SIN key, things like inverse functions e.g., SIN1 or lesscommon functions e.g., the v will be listed above other keys. Whenever you type a left parenthesis, you must close it with a right one; similarly, if you type a total of five left parentheses, youll have to close them with five right ones.You can change between displaying values in terms of degrees of 360 or radians decimals using as the basis by pressing the MODE key, using the arrow keys to select RADIANS or DEGREES, and pressing the ENTER button.If you notice that your equations are returning decimal values instead of degrees or vice versa, youll need to change this setting. Saving your results and pulling them back later is an essential skill for dealing with longer problems. There are a couple of different ways to use stored informationRead on for another quiz question. If youre looking for a specific function on your calculator and dont see it right away, it might be a secondary function. Click on another answer to find the right one.

For example, you might try taking the square root of 9; you should already know that the answer will be three, so this is a great tip to use in the middle of a test if you forget which order youre supposed to be pressing buttonsIf you get 8 as the answer, then you did it in the right order. If you got 9, then you actually did 3 2. When you are using the SIN, COS, or TAN functions, you will have to keep in mind two different things the order of the button presses, and radians versus degrees.If pressing SIN and then typing in 30 gets 0.5 as an answer, then your calculator is set to display in degrees. If your answer is .988, then your calculator is set to radians. Things can get a bit more complicated when you start entering longer equations into your calculator. You will need to take order into consideration, and will often make use of the keys.Proper parentheses use is essential to successfully using the calculator. While things like SIN, square roots, inverse exponents, and pi are often either represented by keys or secondary text above keys, you can find more advanced functions e.g., factorials in the MATH menu. To use the MATH menu, do the followingCalculating the power of a number is a little different. Try again. Look for a different button instead of an assortment of smaller numbers. Click on another answer to find the right one. Test it a couple of times with easy numbers to make sure youre getting the order correct. Read on for another quiz question. There is a button specifically for creating exponents. Pick another answer! This will show you the curve of the graph and its general position.This will pull up a list of points on your graph that you can scroll through. Read on for another quiz question. Guess again! It can change the a number from decimal to or . It can also solve equations. Some scientific calculators allow you to store your own formula as well. Most are capable of calculating , index and root.http://daonshop.com/files/fckeditor/eboost-street-manual.xml

If you have a modern calculator, there should be a log button with two blank rectangles allowing you to input the base and the output to find the power.This will give the required answer. For example, to find the 5th root of 1048576, take its and divide by 5. Take the antilogarithm of this result and you will have your answer.The top box represents the numerator, and you need to press the down arrow to access the denominator. If the key is not present, you need to just use the divide key. Your calculator should have come with a manual that might point out a specific button for this function if you cant find the one I described.Refer to the manual if you cant find a specific function that you know should be there. This article has been viewed 342,968 times.Additionally, familiarize yourself with the secondary functions above the primary keys, which can be accessed by pressing the “Shift” or “2ND” key. When dealing with longer problems, use the answer function to recall the last displayed answer to an equation. If you need to clear the screen, press the “Clear” button near the top of the keyboard.

Use the left arrow key to select FLO.The display shows TAB09. Enter the number of digits you want after the decimal point. When all else fails, READ THE MANUAL. Does the job, I am taking advanced calculus classes and linear algebra and this does the job.Its more like a mini computer than a calculator. So many functionalities and capabilities. Perfect for an student. Has a lot of memory.

Solar panel so no need to change batteries. Super justifiable cost!Its pretty decent.I have a few different ones in this series, including the write view versions. Phenomenal calculators.So you would basically input the values as you would write them i.e. put the square root symbol in front of the value instead of after. My only gripe is that its quite large.Easy to use, nice packaging and most important they provide the functions that are needed,It works so it gets 5 stars.My coworkerengineers told me that they would not be allowed to use that kind of calculator on their exams. The gadget is accompanied by very elaborated user guide that was well worth reading, and by the end of the reading, I felt like I scrubbed off some rust that covered my knowledge. The hard case and the total light weight are very much appreciated.This is the reason why this mobile is eligible for use in most of the exam settings, I think. I use it frequently for tutoring . Very easy to calculate Z, binomial and poisson probabilities. I wish it had F, Chisquared and T tables as well, it’s very easy to implement as this calculator has relatively powerful processor.These calculators seems to last for a couple years, which is great. My only complaint is that my last two both decided to die during an exam. Cmon, really I personally purchased and paid for this item at amazon.ca verified purchase . It should be noted that I only use a calculator for basic calculations and I have absolutely no idea or knowledge if this calculator has any advanced abilities or functions for accounting or business applications. The calculator according to the box was made in China and has limited instructions in both English and Chinese.. full review. In most cases, the standard mode for a scientific calculator is degree mode, but if you frequently change between different forms of angle measurement, then you need to learn how to switch modes.Calculate sin90 and view the result.

On calculators, it tends to be the first method, but on others, like the calculator included with Windows, its the latter method.If none of these approaches works, find the manual for your specific model to learn the button combination. She has 15 years of experience teaching collegiate mathematics at various institutions. We will then look at how to use exponents on a scientific calculator and look at a couple of examples of doing so. Some would say theyre creepy while others admire their work ethic and even think theyre a little cute. Lets say that you decide to study these little guys for the next six months, so you make an ant farm. You start with just two ants in your farm, and soon realize that they are increasing in number in such a way that their population doubles each week. When we are multiplying an expression, call it a, by itself a number of times, that number is called an exponent. We say that we are raising the expression to the power of the exponent, and we write a x where x is the exponent. To put this into perspective, consider your ants again. We said that to find the population of ants, we multiply 2 by itself the number of weeks that have gone by. If we call the number of weeks that have gone by w, then we have that the population is 2 w. Using Exponents on a Scientific Calculator Its pretty easy to find the ant population for the first few weeks. However, what if we wanted to know what the population would be after 8 weeks. We would want to find 2 8, and that would mean multiplying 2 by itself 8 times. I dont know about you, but doing this by hand seems like a tedious job to me. Even if we use a basic calculator, our fingers might get sore from having to push 2 times 2 times 2 times 2, and so on. Thankfully, theres an easier way the scientific calculator! Thankfully, these types of calculators are able to deal with exponents with a few simple keystrokes. The exponent button varies on different scientific calculators.

It may be that you hit the button x, then hit your exponent button, then hit the button y. Or, you may enter your exponent y first, then your exponent button, then x. It could also be that you hit your exponent button first, then x, then y. Uh, all these options are kind of making things confusing. Dont worry! Your calculator manual will tell you how to calculate exponents on your calculator. For now, we will just consider the most common keystroke pattern for calculating x y, and that is as follows Awesome! Lets look at some different ant populations depending on how long youve had your ant farm. Examples We were talking about what the ant population would be at 8 weeks, so we want to find 2 8. To figure this out, we grab our trusty scientific calculator and plug away. First, we enter the number 2. Next, we hit the exponent button then enter the number 8. Lastly, we hit Enter. Wow! Your ant farm is booming. Things are going great. Lets consider how many ants there will be at the end of the project. That will be in 6 months, or about 26 weeks. To find this, we simply raise 2 to the power of 26, or find 2 26. Thats a lot of twos. Thank goodness for our scientific calculator. We punch in the button 2, then the exponent button, then 26, and lastly, we hit Enter. Yikes, thats a lot of ants. You may need to cut the project short. Lesson Summary Exponents are numbers we raise other numbers or expressions to, indicating the number of times that we want to multiply the number or expression by itself. This can be a tedious job when we have large exponents. Thankfully, there are calculators that can handle these types of problems quite easily, and those are scientific calculators. A scientific calculator is a calculator that is capable of performing operations that are more advanced than simple addition, subtraction, multiplication, and division, but does not have graphing capabilities.

To use a scientific calculator to calculate x y, the most common keystrokes we use are as follows You can test out of theAnyone can earn. The level of information is primarily that needed for introductory . There is a form, which guides people to figure out the key features of their calculator.

I remember a man coming to my eighth grade math class in 1970 or 1971 and showing us a desktop electronic calculator costing hundreds of dollars. I was amazed. It did the difficult math we were doing almost instantaneously. While I was in high school 19711975 the first pocket calculators came out. My dad got the family a Sharp ELSI 8107 with basic operations when I was a senior in high school. Not having a calculator for math through grade 12 made me good at doing hand calculations, and gave me a great appreciation for calculators. The largest holdings are Texas Instrument TI calculators. I have divided the TI calculators by type of display, LED or LCD. LED stands for light emitting diode. With LED displays the numbers light up in red. LCD stands for liquid crystal display. LCD displays usually have black numbers against a silver background. At the time of LED displays, there were also vacuum fluorescent displays displaying greenish or bluish numbers. LCD displays rapidly took over since they use a tiny fraction of the energy of a LED or fluorescent display and hence batteries rarely need to be replaced.

LCD calculators are also much smaller. For more information on display techonology see Museum of Soviet Calculators on the Web with a reprint of an article in International Calculator Collector Spring 1997. My collection represents only a small fraction of TI calculators. For very comprehensive and detailed information on TI calculators, I recommend you browse through www.datamath.org. My museum also contains sections for calculators from Sharp, Casio, Hewlett Packard and other manufacturers. Where I could find or remember information, I have included the approximate price of the calculators. It is striking how rapidly prices declined. Visit often. Additions are made every so often. Donations of vintage calculators are also always gratefully accepted. My TI 2500 is in good working condition. Be sure to check out the history section of www.datamath.org for an excellent discussion of the development of the Datamath calculator and TIs two desktop calculators, the TI 3000 and TI 3500 introduced at the same time. Manual Cover, Datamath Box. Different versions manufactured from late 1972 to 1975. Battery compartment is heavily corroded. Also, there may be some corrosion near the negative terminal on the circuit board itself. See internal view. Click on Datamath Internal Views for interior views of the three versions. The original NiCad batteries were removed and there is some corrosion. It works with three AA batteries, however. It comes with a charger which cannot be used without the NiCad batteries. This example works well. Another example a gift does not have the rechargable battery. Manual Cover, Box, Case. Datamath.org has excellent and detailed information about the TI SR50. It is also designed to work with three NiCad batteries.Manufactured in 1975. One 9 volt battery. Working, except display is cracked.One nine volt battery. I have several working examples, one with one LED cell broken. One belonged to my fatherinlaw. Case and Manual. BP6 battery pack discharged and shows corrosion. The battery pack is 2.4 volts. I took two modern 1.2 volt AA rechargeable NiMH batteries and put them in a battery holder I got with a model electric car kit. I put the two wires that attach to the battery holder into the two central holes in the calculators battery connector experimenting to see which wire went into which hole. I held the battery holder in with clear packing tape. The calculator now works perfectly. The NiMH batteries can be removed and charged in their own charger. Originally it used a BP77 rechargeable battery pack but the seller converted it for use with a 9 volt battery. See datamath.org for more details. In very good working and cosmetic condition. Runs on one 9 volt battery. It does not have trigonometric and log functions, however. It is in excellent working condition with the internal rechargeable batteries still holding a charge. Serial number 80624. Datamath.org has excellent information including xray images and internal views. Purchased on eBay in 2005. In good cosmetic and operating condition without the booklet. While most early TI calculators had LED displays, the 1025 has a fluorescent diplay. As a step up from the 1000, this includes a square root key and memory. From the wear on the keys you can tell this calculator was well used. Part of the lot of 24 calculators referred to with the TI 1000 above. Ebay description said it worked with an AC adapter not provided. I replaced it with a AA NiMH battery. I used the old battery to wedge the NiMH battery in place. After playing with the metal tabs a bit, I got it to work. You would not charge the battery in the calculator with this arrangement. Datmath has nice photos of all TI battery packs. Significant bright blue corrosion in battery compartment. Originally did not work with batteries. I chipped away the corrosion, however, and it works fine now. Excellent cosmetic and working condition. No corrosion in battery compartment.

It was one of the last of the Datamath series. A great deal! Serial no. 2510010203. Can use adapter 9180.Assembled in USA. Operates on one 9 volt battery. Also, the battery cover does not latch properly. Assembled in USA. Serial No. A 1808220. Mine is a late run of the original version with AC input or 4 C batteries and a headphone jack. Datamath also has extensive internal photos. As explained in Datamath, this toy used recently invented voice synthesization to say letters and words. It included several different types of word games. Pretty cool since home was far away. Mine was purchased on eBay in 2005 or 2006. It is in good cosmetic condition. The battery cover is missing. Originally it worked only with an AC adapter. There was some corrosion on one of the battery compartment terminals. With some Aluminum foil wedged in I finally got it working. It is serial no. 5546862 and was assembled in the USA. Back removed. Purchased on eBay. Excellent working condition. The manual is available as a pdf document at www.datamath.org. The TI 3500 had a 10 digit display instead of the 8 digit display of the TI 3000. The TI 3500 also had switches to change the decimal point and to switch between chain or constant calculations. The manual is available online as a pdf document at www.datamath.org. Good working condition. It was introduced in June 1978. It was inexpensive to build and used less than one thousandth of the energy of the Datamath just six years earlier. According to the Datamath site, 0.4mW compared to 550mW. Batteries now lasted years instead of hours.It has been very reliable. Good working condition. Quizes you on math facts. Does not do decimals. Batteries have leaked. First introduced in 1999 along with several other two line display calculators. Two line display is very handy. Stokes Publishing Company makes an overhead projector calculator with the same key functions. This is a student donation.

Note the beautiful white, gray and green motiff although it is not purple or lime green. This is the earlier of two TI 81 designs. I believe it was orginally several hundered dollars with the viewing screen. Both the calculator and the screen are in good cosmetic and working condition except for identification markings from the school it was used at prior to being disposed of as surplus. It also came with a Poloroid magnifier to magnify the view screen image and a hard plastic case, padded inside, to store all the items. The TI 83 has a Z80 family processor, like the Kaypro II computer. The combined RAM and ROM of TI 83 Plus is nearly ten times that of the Kaypro. As I recall, purchased on eBay. Today, most calculators are made in China. 8 digit LCD display with solar power no battery backup. Comes with a grey plastic folding case which was directly attached to the calculator. The case is now torn off from the calculator. Date is from datamath.org which also indicates this is the second of two versions of the TI 5008. It represents quite a change from the Pocketronic 12 years earlier. In good working and cosmetic condition. The printing mechanism moves although I do not have a paper test to fully test it. Uses three AAA batteries.Similar to the TI 5008 above with some of the financial capabilities and styling of the TI BA35 above. Takes 4 AAA batteries. In very good cosmetic and working condition except the print is light I assume the thermal paper is too old, the label on the back came off and is taped back on, and there are two velcro strips firmly attached to the back. See datamath.org for more information. Mine was purchased on eBay and is in good working and cosmetic condition. It has a green fluorescent display with strange shaped numerals including half height zeros. It is in excellent cosmetic and working condition. A great piece of calculator history! Other images bottom, label This was followed by the Sharp EL811 around early 1972.

It was one of the first handheld calculators with a memory. The EL811 used two large scale integrated circuits instead of the four used by the EL8, showing the rapid progression of integrated circuits in the early 1970s. The EL811 continues to have the strange shaped numerals of the early Sharp calculators including the half height zeros. I believe it may have been the last Sharp calculators to have these strange shaped numbers.The calculator does not work with the power supply which only appears to output 1.47 volts. The NiCad battery pack was badly corroded. I replaced it with an inexpensive battery pack for five AA 1.5 volt disposable batteries. Internal View. This provides approximately 7.5 volt, slightly over 7.2 volts originally provided by the 6 batteries in the NiCad battery pack. Alternately, you could use a battery pack for six AA NiMH rechargeable batteries which would give 7.2 volts. I dont think you could use the original power supply to charge them, however. My calculator works fine with the 5 disposable batteries. Unfortunately, I had to cut off the connections for the original battery pack. I then simply connected with wires with small electrical nuts. The calculator comes with the original case which included two pieces of paper one with printed logarithmic tables and one with handwritten notes on calculus and other formulas. With simple calculators like this the logarithmic tables were still needed. Once scientific calculators came out, logarithmic and trigonometric tables were no longer needed. Most advanced math books at the time had log and trig tables in the back. The first is the Lloyds Accumatic 100, produced by Rockwell in 1972, according to Vintage Calculators. My Sears C1 appears to be a variant of the Accumatic 100. See www.dentakumuseum.com in Japanese. The EL805 employed a crystal on substrate design with silver numbers against a black display. See additonal EL805 pictures at datamath.org.

The processor and LCD were on a single piece of glass. It used a tiny fraction of the energy of an LED calculator and could operate on a single AA battery for 100 hours. The back states it used.02 Watts which at the time was an amazing feat. Sharp LCD Calculators and Vintage Calculators have excellent information about the history of Sharp LCD calculators. Wikipedia has information about LCD technology. The photo is just fuzzy. Excellent cosmetic condition except for light scratches on the back and a name and social security number lightly scratched onto the back. Soft case and instruction manual. Flip up cover over the display like the EL808 below. Much smaller that the EL808, with dimensions of approximately 8cm x 12cm x 2cm. The Crystal on Substrate COS LCD display shows numbers in silver against black in contrast to black against silver today.Excellent working condition. This is the same model as the first calculator my family ever had in late 1974. While not rare, one site indicates it has a ceramic NEC CPU, unusual at the time. Green fluorescent scientific calculator lacks , however. 4 AA 1.5 volt batteries, five 1.2 volt rechargable batteries or AC Adapter. Purchased on eBay about 2003. Very good working condition. For more information, see Old Calculator Museum. It has held up ever since that time. It replaced a broken Commodore LED scientific calculator purchased two years earlier. Sharp was a leader in LCD calculators with early models dating back to the early 1970s. See Sharp LCD Calculators. Also compares unit costs for the best deal. Purchased with the EL819. Like new condition. Wallet like case and instruction manual. Excellent working condition after a little tinkering and disassemby. It needed new batteries and one battery clip was not connected to the contacts below. The components are sandwiched together with no soldering. The display and the processor fall right out. The battery clip needed to make contact with this piece.

Photo 1, Photo 2, Photo 3.Tone sounds as each key is pressed. This feature is easily shut off with the musical note toggle key. It is in good cosmetic condition and excellent working condition. Comes in a wallet case which feels like leather on the outside.Finds LCM or greatest common factor GCF. Does scientific notation and simple statistics.Very helpful with middle school math and displaying fractions. I then discovered that the mixed number key also does not work. Photos Showing EL E300 Disassembly. I find them to be curious but not very practical since the buttons and display are so small it is difficult to use. They demonstrate that the size of calculators and computers is often not governed by the processor, but rather the human interface. In excellent working and cosmetic condition. Relatively compact with typical scientific functions and wallet style case. Date is likely approximately 1986 since I found a book on the Internet called Conquering the , Applications for the Sharp EL509S, with a publication date of 1986. Takes two AA batteries. Battery compartment is clean. It is unique because it takes a 9 volt battery, a very large power source for an LCD calculator. The space for the battery requires a large bulge on the back of the calculator as seen in this profile. Its power consumption at.038 Watts the last digit is hard to read is over 100 times more than the Sharp EL230 to the right. It is still close to 10 times less than the EL8118 above, however, which consumes.3 Watts. Purchased in the same lot as the EL8118. It is in good cosmetic condition except for what looks to be some melted plastic on the back. It does not operate since one of the battery connections is corroded. However, I cut through the plastic on the connector and held the battery up to the back side of the connections. The calculator works fine doing that. See photo Installing a new 9 volt snap connector should therefore allow it to function like new.
