## anonymous 4 years ago sin^-1(-.18) = -.18 correct?

1. bahrom7893

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

2. anonymous

unlikely

3. TuringTest

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

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

5. TuringTest

$\sin x=x$only has one solution: x=0
