The Mean Value Theorem generalizes Rolle's theorem by considering functions that do not necessarily have equal value at the endpoints. Consequently, we can view the Mean Value Theorem as a slanted version of Rolle's theorem (Figure 5).

Figure 3.6.5: The Mean Value Theorem says that for a function that meets its conditions, at some point the tangent line has the same slope as the secant line between the ends. For this function, there are two values c1 and c2 such that the tangent line to f at c1 and c2 has the same slope as the secant line.

Which theorem came first: Rolle or Mean Value?

2. Yes and No: Rolle's theorem did come first, but it was NOT used to prove the mean value theorem (MVT) when the MVT was first proved. The insight that the MVT is reducible to Rolle's theorem seems to have come later. At the end of the 19th century the MVT was still research-level material. The burning issue of the day was whether the …

ROLLE'S THEOREM AND THE MEAN VALUE THEOREM

For the c given by the Mean Value Theorem we have f′(c) = f(b)−f(a) b−a = 0. So the Mean Value Theorem says nothing new in this case, but it does add information when f(a) 6= f(b). The proof of the Mean Value Theorem is accomplished by finding a way to apply Rolle's Theorem. One considers the line joining the points ha,f(a)i and hb,f(b)i.

Mean value theorem (old) (video) | Khan Academy

However, the mean value theorem does not assert that the derivative of ƒ is zero at some point. It asserts the following. Let a and b be two real numbers such that a < b. ƒ is clearly continuous on [a, b] and differentiable on (a, b). By the mean value theorem, there exists some real number c such that a < c < b and ƒ(b) - ƒ(a) = ƒ'(c)(b - a).

Mathematics | Rolle's Mean Value Theorem

So, we can apply Rolle's theorem, according to which there exists at least one point 'c' such that: f ' (c) = 0. which means that there exists a point at which the slope of the tangent at that is equal to 0. We can easily see that at point 'c' slope is 0. Similarly, there could be more than one points at which slope of tangent at ...

Calculus I

What the Mean Value Theorem tells us is that these two slopes must be equal or in other words the secant line connecting A A and B B and the tangent line at x =c x = c must be parallel. We can see this in the following sketch. Let's now take a look at a couple of examples using the Mean Value Theorem.
