WebYou have d v = x ( a 2 + x 2) − n d x. When you integrate, you add one to the exponent. But adding one to − n gives − n + 1 = − ( n − 1). So v = 1 2 ( − n + 1) ( a 2 + x 2) − n + 1 = 1 2 ( 1 − n) ( a 2 + x 2) n − 1. The minus sign from integration by parts can be cancelled out by switching the sign of 2 ( 1 − n) to get 2 ( n − 1) = 2 n − 2.
