Question

sin^-1(-.18) = -.18

correct?

Answer 1

No.. why? I mean i don't know but in general, Sin^-1(x) does not equal x

Answer 2

unlikely

Answer 3

\[\sin^{-1}x=\theta\]tells you what angle theta gives you the value sin(theta)=x
example\[\sin(\frac\pi2) =0\to\frac\pi2=\sin^{-1}0\]

Answer 4

I'm just punching this in the calculator and that is answer I got. I was just startled that x and the answer were the samee

Answer 5

\[\sin x=x\]only has one solution:
x=0
