derivative of cot x with respect to x

Here you will learn what is the differentiation of cotx and its proof by using first principle. Let’s begin – Differentiation of cotx The differentiation of cotx with respect to x is \(-cosec^2x\). i.e. \(d\over dx\) (cotx) = \(-cosec^2x\) Proof Using First Principle : Let f(x) = cot x. Then, f(x + h) = cot(x …
