## FAQs on Mean Value Theorem Video Lecture - Mathematics (Maths) Class 12 - JEE

 1. What is the Mean Value Theorem in calculus?
Ans. The Mean Value Theorem is a fundamental theorem in calculus that states that if a function is continuous on a closed interval [a, b] and differentiable on the open interval (a, b), then there exists at least one point c in (a, b) where the instantaneous rate of change (the derivative) is equal to the average rate of change (the slope of the secant line).
 2. How is the Mean Value Theorem useful in calculus?
Ans. The Mean Value Theorem is useful in calculus as it guarantees the existence of a point where the instantaneous rate of change equals the average rate of change. This theorem helps us establish connections between the behavior of a function and its derivative. It is often used to prove other important theorems and to solve various problems in calculus, such as finding maximum and minimum values of a function.
 3. Can the Mean Value Theorem be applied to non-differentiable functions?
Ans. No, the Mean Value Theorem can only be applied to functions that are differentiable on the open interval (a, b). If a function is not differentiable at any point within the interval, then the conditions of the Mean Value Theorem are not satisfied, and the theorem cannot be applied.
 4. How is the Mean Value Theorem related to the concept of a tangent line?
Ans. The Mean Value Theorem is closely related to the concept of a tangent line. The theorem guarantees that there is at least one point within an interval where the derivative of a function equals the slope of the secant line connecting the endpoints of the interval. This means that at this point, the tangent line to the function is parallel to the secant line, illustrating the connection between the derivative and the slope of the tangent line.
 5. Can the Mean Value Theorem be used to determine the exact value of a function at a specific point?
Ans. No, the Mean Value Theorem does not provide information about the exact value of a function at a specific point. It only guarantees the existence of a point where the instantaneous rate of change equals the average rate of change. To determine the exact value of a function at a specific point, additional information or techniques, such as evaluating the function or solving an equation, are required.
