Theorems
| Question | Answer |
|---|---|
| Mean Value Theorem (MVT) | f'(c) = f(b) - f(a) / b - a |
| What does the MVT say? | There is a value c in the interval (a,b) such that the instantaneous slope equals the average slope |
| What does the IVT say? | For any number N between f(a) and f(b), there exists at least one number c in (a,b) such that f(c) = N |
| What does the EVT say? | A function f attains both an absolute minimum and an absolute maximum on the interval [a,b] |
| What is the MVT used for? | To find where the slope of a tangent line equals the slope of the secant line |
| What is the IVT used for? | To prove that a function hits a specific value within an interval |
| What is the EVT used for? | Guarantees absolute extrema exist, found by checking critical points and endpoints |
