how do you integrate x tan^{1}x dx, i know it can be done by integration by parts maybe, but i'm not sure.... i'm a student studying for a test.
Hi,
Integration by parts is the way to solve this problem. I let u = tan^{1}x and dv = x dx which leads to
You should check your answer by differentiating or you can try The Integrator. The input is x*ArcTan[x], the capital letters and square brackets are required. (The arctangent
or inverse tangent is written tan^{1}
rather than arctan in many textbooks.)
