Question

state the unit circle cosine (x) and sine (y) values for the following angles:
theta = 0 degrees
theta = 30 degrees
theta = 45 degrees
theta = 60 degrees
theta = 90 degrees
theta = 120 degrees
theta = 135 degrees
theta = 150 degrees
theta = 180 degrees
theta = 210 degrees
theta = 225 degrees
theta = 240 degrees
theta = 270 degrees
theta = 300 degrees
theta = 315 degrees
theta = 330 degrees

Answer 1

This is not too difficult, it is just remembering a pattern.

Answer 3

thank you so much!

Answer 4

But if you need it on a test I found a technique on YouTube that works really well for finding the exact values of the unit circle values. http://www.youtube.com/watch?v=ZerlFfNZeQg

Answer 5

actually I need help with the values on this circle
