<p> Modeling Real World Data with Trig Functions NOTE: PLEASE DO NOT WORK AHEAD OF THE GROUP</p><p>1.) Open the Ferris Wheel Simulation in Geometer’s Sketchpad from my Web Page</p><p>2.) Look at the top left for the point C(-20, 23). What does this point represent?</p><p>3.) Click What does Angle (C) measure?</p><p>4.) Click What do the coordinates of S measure ?</p><p>5.) Stop the ferris wheel (re-click ) 6.) Click outside the sketch to un-highlight the things in pink 7.) Click and drag the line containing point S to the y-axis 8.) Move student B to the highest point above the ground. How do you know that this is the highest point ?</p><p>What are the coordinates of this point?</p><p>9.) Move student B to the lowest point above the ground. How do you know that this is the lowest point ?</p><p>What are the coordinates of this point?</p><p>10.) Select Display/Erase Traces 11.) What does S: (0, 3) represent in terms of the ferris wheel? Modeling Real World Data with Trig Functions</p><p>12.) Click . Stop the curve when the time is under 20 seconds. Paste a picture of your graph below. What is the height of student B above the ground? _____. What does that point represent? </p><p>13.) Click . Stop the curve when the time is under 40 seconds. Paste a picture of your graph below. What is the height of student B above the ground? _____. What does that point represent? </p><p>14.) Stop the animation before 60 seconds and paste a picture of the graph below.</p><p>15.) Amplitude = ______. Explain what the amplitude of the graph represents in your own words.</p><p>16.) Period = ______. Explain what the period of the graph represents in your own words.</p><p>17.) Click . Start and stop the ferris wheel about 20 times to record about 20 ordered pairs for point S.
