Using the Unit Circle Find the Exact Values of:

1. 5(pi)/3

2. 5(pi)/6

3. -pi/4

4. -2(pi)/3

I'm sorry I can not find the "pi" symbol

These are exact values! Presumably, you mean that, given they are angles, what are their values in degrees?

¶ radians = 180° so

1. 5¶/3 radians = 5*180/3 = 300°

etc.
