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 $\displaystyle \int{\frac{y^2}{1 + x^2}\,dx} = y^2\int{\frac{1}{1 + x^2}\,dx}$.
Does that look familiar?
