    Just as an alternative for you guys if you want to use it, I have stumbled upon another way of integrating by parts/evaluating indefinite integrals.
    Might not be always as convenient as the normal means, but here goes. Good luck at Uni .

    \int u(x)v(x)\ dx = u(\int v(x)\ dx) - u'(\int\int v(x)\ dx) +k

    I may be wrong with this assumption. Always ready to be corrected, but it seems to churn out correct answers for my integration.

    Integration by parts, those parts being (x^2n) and (x/root(1-x^2)) respectively
