## Differentiation of sinx

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