The trick is to think of the function as a product of arctan(x) and 1, both with respect to x. We solve the integral by choosing to integrate 1 to x and differentiate arctan(x) into 1 1 + x2 which is easier to integrate: ∫arctan(x) ⋅ 1 dx = xarctan(x) − ∫ x 1 + x2 dx + C0 and we ...

WebThere's an angle in QII, namely 135 degrees, whose tangent is -1, and there's an angle in QIV, namely 315 degrees (or -45 degrees, if you prefer) whose tangent is -1. In order for arctan to be a function, arctan(-1) must have just one value, and the same has to be true for arctan(x), no matter what real number x stands for.
