The graphs of cosine and sine, plotted versus the angle θ, look like: where cosine is in green and sine is in red. The reader should compare the values on the graphs above, for the first 90 degrees, with those obtained earlier and put into the table. θ sin(θ) cos(θ) 0° 0 1 30° 45° 60° 90° 1 0
Notes on Find That Side or Angle Learning Task
Graphing calculators include keys to give values for the sine, cosine, and tangent functions that are very accurate approximations for all trigonometric ratios of degree measures greater than 0° and less than 90°. You should use calculator values for trigonometric functions, as needed, for the remainder of this task.

1. Calculate the sine, cosine, and tangent to angle G and the corresponding angles of your similar triangles using your calculator or using Sketchpad’s calculator. Be sure the grader can see and identify your calculations. Using Sketchpad and transformations, create two triangles similar to the one below.

Exploring Sine and Cosine Graphs Learning Task: In the previous task you used your calculator to model periodic data using a sine graph. Now you will explore the sine, cosine, and tangent graphs to determine the specific characteristics of these graphs. Using your knowledge of the unit circle, complete the following chart for f(x)=sin x.

Making use of sine and cosine functions. Your calculator handles sin and cos functions just like the tan function. Which function to use depends on which two side-length measurements you know (or want to find out), and where those sides are compared to the angle whose size you know (or want to find out).

Set m(A to 90°. What is tan 90°? Explain why this is true. Turn off Show tangent computation. Set m(A to each of the following angles, and use the side lengths and a calculator to find the tangent of each angle. Use the Gizmo to check. tan 15° = tan 45° = tan 60° = tan 75° = Why does tan 45° = 1? (Activity C continued on next page)
