Differentiation of cotx

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 …
