Consider the definite integral [tex]\int \frac{(x^3)}{(sqrt(3x^2-1))}[/tex](adsbygoogle = window.adsbygoogle || []).push({});

can someone help me find the appropriate subsitution?

i know that i will need this subsitution:

[tex]sqrt(x^2-a^2)[/tex] is equal to

[tex]x=a*sec(theta)[/tex]

well... i have to make 3x^2 look like x^2 somehow.

i tried using u-du sub, but i cant really find the right subsitution.

can someone give me a hand?
