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

To integrate cosec^2x, also written as ∫cosec 2 x dx, cosec squared x, cosec^2 (x), and (cosec x)^2, we start by using standard trig identities to simplify the integral. We recall the standard trig identity for cosecx, and square both sides. We divide …

The basic trigonometric identities are: Cosec θ = 1/Sin θ Sec θ = 1/Cos θ Cot θ = 1/Tan θ Tan θ = Sin θ/Cos θ Cot θ = Cos θ/Sin θ Sin2θ + Cos2 θ = 1 1 + tan 2 θ = sec 2 θ
