The question is something like this, find the:(adsbygoogle = window.adsbygoogle || []).push({});

d/dx of sin^{-1}(X+a) /b.

then evaluate,

intergarte of X / (9-4x-x^{2})^{1/2}

&

intergarte of X^{2}/ (9-4x-x^{2})^{1/2}

What i get for the first part is,

d/dx of sin^{-1}(X+a) /b = 1 / ( -X^{2}/b^{2}-2aX/b^{2}-a^{2}+b^{2}/b^{2})^{1/2}

Then i'm stuck. xD

Sorry for the confusing equation.
