See all questions in Integration by Trigonometric Substitution Impact of this question 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. 2015-10-23 · See the explanation section, below. Rewrite the integrand using tan^2x = sec^2x-1.
