Hi, I have been given the task of converting this integral:

$\displaystyle \int_0^1\int_{y^2}^{\sqrt{y}}(x+y) dx dy$

Into polar coordinates. I don't really know where to begin. I found that

$\displaystyle \sqrt{y}=x$ is equal to$\displaystyle tan \theta sec \theta$ and

$\displaystyle y^2=x$ is equal to $\displaystyle cot \theta csc \theta$,

But I don't know how that might help me. Any help?

Thanks,

Peter
