Med partiell integration ges en möjlighet att integrera (bestämma primitiv funktion) till vissa produkter av \int sinx⋅x \, dx = (-cosx)⋅x – \int (-cosx)⋅1 \, dx $

2018-02-26 · In order to calculate this integral you may use the following transform. #t=tan(x/2)# hence. #sinx=(2t)/(1+t^2)#, #cosx=(1-t^2)/(1+t^2)#, #dx=2/(1+t^2)dt# After some basic calculations which means just replace the above values to the integral and deduce you will get

Om r(u,v) är en rationell funktion i u och v, så kan man alltid överföra en integral av formen ∫ r(sin x,cos x) dx på en integral av en rationell funktion i t med hjälp I. Evaluate the integral. 1. ∫ xcos(x)dx. Answer: ∫ xcos(x)dx u = x dv = cos(x)dx. = xsin(x) -. ∫ sin(x)dx du = dx v = sin(x). = xsin(x) + cos(x) + C. 2.
