derivative of tan inverse

Here you will learn differentiation of tan inverse x or arctanx x by using chain rule. Let’s begin – Differentiation of tan inverse x or $tan^{-1}x$ : The differentiation of $tan^{-1}x$ with respect to x is $1\over {1 + x^2}$. i.e. $d\over dx$ $tan^{-1}x$ = $1\over {1 + x^2}$. Proof using chain rule : Let […]
