, so there exists at c belongs to
We know that cosine and sine functions are continuous and differentiable on R.
Let’s find the values of the function at an extreme
We have , so there exists at , such that
Let’s find the derivative of f(x)
[Multiplying both the sides by]
Hence, Rolle’s Theorem is verified.
