Hello everyone, first post here. I just need some help on this integral. I can't seem to get it right, any help is appreciated. I don't even need a full solution, just give me some hints. Thanks.

$\displaystyle a\not = 0$
First open the parantheses.
$\displaystyle \int
x\sqrt{1-\frac{x^2}{a^2}}dx$
Use substitution function,
$\displaystyle u=\frac{x^2}{a^2}$
The rest is trivial.
