Dear Student,
Rolle's Theorem: It expresses that expecting f be differentiable on the open interim (a, b) and ceaseless on the shut interim [a, b].
At that point if f(a) = f(b), there is no less than one point c in (a, b) where f'(c) = 0.
Lagrange's Theorem: Also known as mean esteem theorem.It states that expecting f(x) be differentiable on the open interim (a, b) and nonstop on the shut interim [a, b]. At that point there is no less than one point c in (a, b) with the end goal that f'(c) = (f(b) - f(a))/(b - a).
Conditions for the two hypotheses is that f must be differentiable on (a,b) and constant on [a,b].
Cheers!!
