CoreDerivatives
Max / Min
Overview
Find local maxima and minima using the first and second derivative tests.
Key Concepts
1
First derivative test: sign change of f′ at critical point
2
Second derivative test: f′′(a) > 0 ⇒ local min; f′′(a) < 0 ⇒ local max
3
Global extrema: check critical points and endpoints
