Derive reduction formula

WebLet’s start replacing 2x 2x for v v, then we derive and clear: dv = 2 \ dx dv = 2 dx \cfrac {dv} {2} = dx 2dv = dx We substitute the integral 2x 2x for v v and dx dx for \frac {dv} {2} 2dv: … 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.
