2019年1月20日 · ∫ csc 2 x d x or ∫ cosec 2 x d x. The indefinite integral of cosecant squared of angle x function with respect to x is equal to sum of the negative cotangent of angle x and a …

2016年11月26日 · How to integrate $\csc (2x)$ by using substitution $t=\tan x$ ? I know a different way to solve it. But the book mentioned must be using substitution of tan x

We get $\csc^{2}(x)=1+\frac{1}{u^{2}}=\frac{1+u^{2}}{u^{2}}$, and $\frac{du}{1+u^{2}}=dx$. Therefore the integral is $$\int \csc^{2}(x)=\int \frac{1+u^{-2}}{1+u^{2}}du=\int \frac{1}{u^{2}}du=\frac{-1}{\tan(x)}+C=-\cot(x)+C$$
