Rewrite the integrand using tan2x = sec2x − 1. Let's give the integral we want the name I I = ∫tan2xsec3xdx = ∫(sec5x −sec3x)dx Next we'll integrate sec5x by parts.

∫tan x sec x sec x - ∫tan x dx. 2009-03-02 · For the best answers, search on this site https://shorturl.im/avdZf. For starters, I want to quote some theorems that I will be using: (1) tan^2(x) = sec^2(x) - 1 (this comes from sin^2(x) + cos^2(x) = 1 being divided on both sides by cos^2(x) (2) d(tan(x))/dx = sec^2(x) (3a) Let u = tan(x), then du = sec^2(x) dx. 2007-03-04 · integrate (tan^ 2 x) dx I believe the answer is tanx - x + c, but I can't be sure.
