Nettettanx/1+tanx = [ (1+tanx)-1]/1+tanx by adding and subtracting 1 in numerator. Now you can integrate easily by substitution of sinx + cosx = t so that (cosx - sinx) dx becomes … Nettet1. Proof. Strategy: Make in terms of sin's and cos's; Use Subtitution. tan x dx = sin x cos x: dx: set u = cos x. then we find du = - sin x dx substitute du=-sin x, u=cos x sin x cos x: …
