The Mean Value Theorem (MVT)

The Mean Value Theorem states that for a continuous and differentiable function on an interval [A, B], there exists at least one point 'c' in (A, B) where the instantaneous rate of change (derivative) equals the average rate of change (secant slope).

💡

Pro Tips

The function must be continuous on [A, B].
The function must be differentiable on (A, B).
Geometrically, implies a tangent line parallel to the secant line.

Fun Facts

"Often used to prove constructibility of roots."
"A specific case is Rolle's Theorem, where f(A) = f(B), implying a horizontal tangent exists."

Formula: f'(c) = [f(B) - f(A)] / (B - A)
