Take out the unit circle you made in Lesson 3: Try This 4. You were able to use this diagram to visualize angles and determine some trigonometric ratios. Another way to visualize some of the same information is to plot a graph of the y-coordinate of the intersection of the terminal arm and the unit circle, P(x, y), versus the angle θ of the terminal arm. Consider these examples:
Open Table and Graph Template.
Save your completed copy of Table and Graph Template in your course folder.
With a partner or group, discuss the following questions based on your graph created in Try This 1.
If required, place a record of your discussion in your course folder.
