derivative of cos inverse x

Here you will learn differentiation of cos inverse x or arccos x by using chain rule. Let’s begin – Differentiation of cos inverse x or \(cos^{-1}x\) : If x \(\in\) (-1, 1) , then the differentiation of \(cos^{-1}x\) with respect to x is \(-1\over \sqrt{1 – x^2}\). i.e. \(d\over dx\) \(cos^{-1}x\) = \(-1\over \sqrt{1 – […]
