If you let u=tanx in integral (tan^2)x you get integral u^2 dx which is not (u^3)/3 c since du= sec^2x dx\\int \tan^{2}x \, dx\ > To integrate tan^22x, also written as ∫tan 2 2x dx, tan squared 2x, (tan2x)^2, and tan^2(2x), we start by utilising standard trig identities to change the form of the integral Our goal is to have sec 2 2x in the new form because there is a standard integration solution for that in formula booklets that we can use We recall the Pythagorean trig identity, and multiply the angles by 2Apr 05, 06 · \\int \\frac{dx}{5 3\\sin x 4 cos x} I know I have to use t =
