    [SOLVED] Question on integrals

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

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

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

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

    No, use a trigonmetric substitution.

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