1. ## Partial integral help

What is the partial integral of y^2/(1+x^2) with respect to x?

Thanks!

I haven't done partial integrals in a while, but if I remember correctly, you treat any other variables except for the one you're integrating with respect to as constant.

So here you'd treat y as a constant.

So $\int{\frac{y^2}{1 + x^2}\,dx} = y^2\int{\frac{1}{1 + x^2}\,dx}$.

Does that look familiar?
