Identity sec2x = tan2x 1 Hence, ∫(tanx)2dx = ∫tan2xdx = ∫(sec2x −1)dx = ∫sec2xdx −∫1dx = tanx − x C Enjoy Maths!$\sin(x)$ and $\cos(x)$ This is since any trigonometric function (that I know of so far) can be written with the basic $\sin(xI had a calculus final yesterday, and in a question we had to find a primitive of $\tan(x)$ in order to solve a differential equation A friend of mine forgot that such a primitive could easily be found, tried to integrate $\tan(x)$ by parts and then arrived to the result $0 = 1$

Integral tan(x/2) substitution
Integral tan(x/2) substitution-1 In general for an integral ∫ a b f ( x) d x to be welldefined, we need ∫ a c f ( x) d x and ∫ c b f ( x) d x both to be welldefined, for all c ∈ ( a, b) This is not the case for ∫ 0 2 π tan ( x) d x since ∫ 0 π / 2 tan ( x) is not welldefined However, the Cauchy principal value is 0, since ∫ 0 2 π tan(Math Calculus Integrals Table Of tan x) Discussion of tan x = lncos x C 1 Proof Strategy Make in terms of sin's and cos's;
