Do you recognize this number(1)? 1.41421 35623 73095 04880 16887 24209 69807 85696 71875 37694 80731 76679 73799 07324 78462 10703 88503 87534 32764 15727 35013 84623 09122 97024 92483 60558 50737 21264 41214 97099 93583 14132 22665 92750 55927 55799 95050 11527 82060 57147 01095 59971 60597 02745 34596 86201 47285 17418 64088 91986 09552 32923 04843 08714 32145 08397 62603 62799 52514 07989 68725 33965 46331 80882 96406 20615 25835 Fig. 1 - HP35s √ key. 23950 54745 75028 77599 61729 83557 52203 37531 85701 13543 74603 40849 … If you have had any math classes you have probably run into this number and you should recognize it as the square root of two, . The square root of a number, n, is that value when multiplied by itself equals n. 2 x 2 = 4 and = 2. Calculating the square root of the number is the inverse operation of squaring that number = n. The "√" symbol is called the "radical" symbol or "check mark." MS Word has the radical symbol, √, but we often use it with a line across the top. This is called the "vinculum" circa 12th century. The expression " (2)" is read as "root n", "radical n", or "the square root of n". The vinculum extends over the number to make it inclusive e.g. Most HP calculators have the square root key as a primary key as shown in Fig. 1 because it is used so much. Roots and Powers Numbers may be raised to any power (y, multiplied by itself x times) and the inverse operation, taking the root, may be expressed as shown below. -

Introduction to UIL High School Calculator Applications Contest
Introduction to UIL High School Calculator Applications Contest Andy Zapata Azle High School Andy Zapata Azle ISD – 1974 to present Azle HS – Physics teacher Married – 4 children & 2 grandchildren Co-founded Texas Math and Science Coaches Association (TMSCA) Current president of TMSCA Coached all 4 UIL math & science events + slide rule Current UIL Elem/JH number sense, mathematics and calculator consultant [email protected] The Calculator Applications Contest is exactly what the title of the contest implies. It is not a mathematics contest where proofs of geometry or algebra theorems are worked out; it is not a typing contest where the fastest button pusher always has the superior score. It is a contest where engineering type problems are solved. I am not an engineer, but I know a few people that do engineering work, and the ability to use the calculator as a tool to solve; or least begin the problem solving process is very important. But I will also be the first to tell you that the problem topics covered in these contest papers cover finance problems, navigation problems, exponential and compound growth and decay problem, problems involving probability and problems involving calculus that go beyond the averaging processes that occur when calculus cannot be used. If you have students that are curious and competitive, they like math and they like to solve problems; then here is a great opportunity for them to flourish and learn more about the problem solving process than they would normally learn in the high school math program. In 1982 I moved up from teaching seventh grade math to teaching a few classes of physics and different math classes until there were enough students taking physics so that I could have all my classes be physics classes. -

A Graphing Calculator for Mathematics and Science Classes
A Graphing Calculator for Mathematics and Science Classes The HP 38G calculator allows teachers to direct students and keep them focused while they explore mathematical and scientific concepts. It features aplets, which are small applications that focus on a particular area of the curriculum and can be easily distributed from the teacher’s calculator to the students’. by Ted W. Beers, Diana K. Byrne, James A. Donnelly, Robert W. Jones, and Feng Yuan The HP 38G calculator is a graphing calculator for students and teachers in mathematics and science classes. It features aplets, which are small applications that focus on a particular area of the curriculum and can be easily distributed from calculator to calculator. This allows the teacher to send an electronic story problem to each student in the class. The HP 38G is built on the same software platform as the HP 48G family of graphing calculators,1 but has a simpler user interface and feature set. Equations are entered using algebraic format rather than the reverse Polish notation (RPN) found in most HP calculators. The features of the HP 38G include: Graphical user interface Function, polar, parametric, stairstep, cobweb, histogram, scatter, and box and whisker plots Side-by-side split screen Tables Unlimited, scrollable history stack Symbolic equations HP Solve numeric root finder EquationWriter display Statistics functions Matrix operations User programming. The hardware platform of the HP 38G is very similar to that of the HP 48G: they both have 32K bytes of RAM, 512K bytes of ROM, the same CPU and the same display (131 by 64 pixels). -
HP Calculator Programming Richard J
HP Calculator Programming Richard J. Nelson Introduction Do you use an HP calculator that has a programming capability, and do you actually use it? Of the 24 models, see Table 1 below, 23 are on the HP website 13, or 54.2%, are programmable. If the Home and Office machines are omitted, the numbers are: 17 models, and 13 or 76.5%, are programmable. What does this mean? A program is a sequence of instructions (functions and/or data) that are keyed (or loaded) into the calculator’s memory that will solve a particular problem or provide specific information. A program capability also includes special instructions that provide prompting for inputs and labeling for outputs. Another aspect of a program capability is the ability to perform decision logic so the particular parts of a program may be changed depending on the results of previous instructions. This capability provides “intelligence” to the program. The program capability of the 10 current models ranges from very simple such as the HP-12C to very complex (and very powerful) such as the HP 50g. Older HP calculators such as the HP-71B or HP-75C used a computer like programming language called BASIC. The HP-12C and HP-15C programing language is an RPN FOCAL(1) like language, and the HP 50g uses an RPL programming language. The algebraic calculators use what may be called an Aplet programming language.

A Hewlett Packard Infrared Signal Decoder
A Hewlett Packard Infrared Signal Decoder Martin Hepperle June 2015 – November 2017 Several Hewlett Packard pocket calculators are able to send printer output via Infra-Red (IR) signals to a small portable printer. They use an HP-specific transmission protocol which is also called “Red Eye”. This protocol is different from the better known IrDA protocol. This document gives a brief overview of the format and describes hard- and software to build a decoder system for this protocol. This system allows receiving the “Red Eye” signals with a computer via a serial or an USB interface. Printers with IR Interface In 1987 HP introduced the small IR printer 82240A (replaced later by the improved variant 82240B). The ON/OFF switch of the printer shows a red dot when in the ON position and the IR receiver is mounted behind a transparent red window. Therefore protocol has been given the nickname “Red Eye”. HP has long discontinued the production of this printer but even today in 2015 you can still find many dealers offering their stock at relatively high prices. There is also at least one manufacturer who offers similar printers with improved technology but still understanding the “Red Eye” protocol. Several rather expensive measuring systems are still in use in automotive and heating system diagnosis so that there seems to be a market for replacement printers. On the other hand you can find used but working printers on eBay for less than 20€, if you are lucky. Figure 1: The HP 82240B printer with its “Red Eye” on/off, darkness and paper advance controls. -
