Question

Find the exact value
sin^1 0

Answer 1

\[\sin^{-1}(0)=0\]

Answer 2

thats it

Answer 3

Yeah, its 0. Because you want "the angle that makes sin(x) zero. Which is zero.

Answer 4

thank u

Answer 5

wat bout this one

Answer 6

You want the "angle that makes sin sqrt(2)/2". You know that sin(pi/4)=sqrt(2)/2. so the ARCSIN(sqrt(2)/2) is pi/4.

Answer 7

pi/4
You should really memorize the values of the special trig functions -- they pop up everywhere and you can derive others from them quite easily when you're taking a test
