Witryna16 lis 2024 · 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. WitrynaIf U ⊂ R n is compact and the only extreme of the continuous function f: U → R on U ∘ is a maximum, then f reaches a minimum at ∂ U. this is just a consequence of Weierstrass' theorem and the fact that U = U ∘ ∪ ∂ U. Since f is continuous and U is compact, it has to reach a minimum on U, which has to be in ∂ U if it is not in U ...
