I need to find the derivative of this.. y = inverse sin of (sqrt(1-x^2)) I got an answer, and in the denominator, I got sqrt(-x^2). This is undefined. Whats going on??

Remember $\displaystyle \frac{d}{dx}\left[\arcsin(u)\right]=\frac{u'}{\sqrt{1-u^2}}du$ In your case...$\displaystyle u=\sqrt{1-x^2}$
