Differentiation of tan inverse x

Here you will learn differentiation of tan inverse x or arctanx x by using chain rule. Letโ€™s begin โ€“ 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 โ€ฆ
