Integrate Surface Integral w/ Jacobian Transformation - Help Needed

[JasonRox]

Everything was going fine until I bumped into this...

(b^2*c^2*Cos[x]^2*Sin[y]^4 + a^2*c^2*Sin[y]^4*Sin[x]^2)^(1/2)

...integrate that with respect to y, for the boundaries y=0..Pi.

A Jacobian Transformation would be a good start, but I have no idea what functions I would use to simplify that in such a way to make it easier.

Any hints would be great.

Nevermind I got it.

I did a little mistake. I miss read the exponents of the previous integral.

Thanks for stopping by though.
