Thread: Calculus

I need to find the limits of the integral, I solved it with polar coordinate (I think it's called like that...) but I'm not sure it's correct.

Do I need to go back to x and y in the solution?

10x.

Is this



Where ?

Yes it is.

Can u see the pic ok, Mathstud28?

Last time u had a problem seeing stuff I scanned.

Next time I'll shrink it a bit.

Can anyone tell me if this correct?

I put a better pic.

10x.

Looks fine except for one small thing - your final answer is missing the r in the integrand from the Jacobian.
