## Differentiation of tan inverse x

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 …
