Question

I could really use some help with this integral using trig identities. I'm terrible with trig. integral of x^2/((9-x^2)^(1/2))

Answer 1

\[\int\frac{x^2}{\sqrt{9-x^2}}\mathrm dx\]

Answer 2

the integral corresponds to the first case in the table ,

so substitute \(x=\frac ba\sin\theta\) . . .

Answer 3

ok...I'm not really sure where to go from there with it though..
