Via integration by parts, we get ∫ 1 − x (x + 1)2 dx = x − 1 (x + 1) − ln x + 1 + C. From this question: evaluate ∫tan(πx)sec2(πx) 2 dx.

NettetU-substitution is the first integration technique that should be considered before pursuing the implementation of a more advanced approach. This technique, which is analogous to the chain rule of differentiation, is useful whenever a function composition can be found within the integrated.
