Question

sin^(-1)⁡(sin⁡〖-135°〗 ) solve for theta.

Answer 1

The answer is an angle measure. But I am confused how to get it. It's 135 or -135 I believe but I need to know how to simplify it.

Answer 2

I'm getting -pi/4, not 135. Maybe I am misunderstanding the question.

Answer 3

I think that is the problem that I am having. I believe that the answer is supposed to be an angle measure.

Answer 4

the instructions say "evaluate the following. answers must be in exact values"

Answer 5

-45 in degrees, again, not 135.

Answer 6

I just want to see how you derived that. I know that it is a 45 degree reference angle and that the -45 degrees is the same as -135 but I need to show it. That is where I am confused.

Answer 7

pi/4 = 45 degrees

Answer 8

ahh, 1 min..

Answer 9

\[\sin^{-1} (\cos(135\deg+\frac{ \pi }{ 2}))\]
