# Thread: [SOLVED] Question on integrals

1. ## [SOLVED] Question on integrals

$\displaystyle \int -3 / sqrt(1-x^2)$

I separate the constant, then move the denominator up to the numerator, getting

$\displaystyle -3 \int (1 - x^2)^{-1/2}$

I'm stuck here though. Do I just apply the power rule?

No, use a trigonmetric substitution.

$\displaystyle x= \sin{\theta}$ could do the trick
