The Attempt at a Solution


so my final answer is

2x4f(x)+4x2f(x)2+2f(x)3
all over
-2f(x)-2x5-4x3f(x)-2xf(x)2

Am i doing it right? I have a feeling I may have misunderstood the question.

so if you differetiate y=f(x) you should get whats below?

LaTeX Code: \\frac{1}{x^{2}+y^{2}}\\ = 2xy


well you can integrate wrt x since function is interms of x. then you can get the original function
