The Mean Value Theorem (MVT) in calculus is a critical concept that links the average rate of change of a function over an interval to the instantaneous rate of change at a specific point. It requires the function to be continuous on a closed interval and differentiable on an open interval. The MVT has practical applications in physics, economics, and everyday life, such as determining a car's speed during a trip or an object's instantaneous acceleration.

The Mean Value Theorem establishes a relationship between the average rate of change and the instantaneous rate of change of a function
Continuity
A function is continuous on an interval if it has no breaks, jumps, or holes in its graph over that interval
Differentiability
A function is differentiable on an interval if it has a defined tangent with a specific slope at every point within the interval
The Mean Value Theorem requires a function to be both continuous and differentiable on a closed and open interval, respectively
The Mean Value Theorem can be used to find a point where the derivative of a function equals the average rate of change over an interval
The Mean Value Theorem can be applied in physics to analyze kinematics and determine instantaneous acceleration
The Mean Value Theorem has practical applications in fields such as economics and daily experiences, such as driving a car
The Mean Value Theorem highlights the significance of derivatives in representing the instantaneous rate of change of a function
Leveraging Rolle's Theorem
The Mean Value Theorem can be proven by using Rolle's Theorem, which is a special case of the MVT
Construction of an Auxiliary Function
The proof of the Mean Value Theorem involves creating a new function that incorporates the conditions of continuity and differentiability
