## Homework Statement

a sample problem: arcsin(-1/2)

**2. The attempt at a solution**

do i look at the unit circle and find the y-coordinate or x-coordinate that has -1/2?

i did ASTC, and figure that it'd be in either quad 3 or quad 4; to tell you the truth i don't understand how to use the unit circle to figure this out.

i can enter it in the calculator but my calculator doesn't change the answer into a function, for instance 9pi/5 or 5pi/6 or 5pi/7
