I have a problem that I'm having a lot of problems trying to solve. I found the answer to it on the online integrator but I don't understand the work behind it. I someone could explain the math behind it that would be greatly appreciated. Question: 1/(1+x^2)^2 ans: [x/(2(1+x^2))]+[(arctan x)/2] Thanks, Tom
