MATSEC AM Pure Mathematics Complete Prep Course — Lesson 70: Stationary points and curve sketching

Sarah Mitchell shows how to locate stationary points by setting the first derivative to zero and substituting back for the y coordinate, then classify them with the second derivative and, when that returns zero, with the sign test. She covers inflexion candidates, increasing and decreasing intervals, and the full sketching checklist of stationary points, intercepts, asymptotes and end behaviour, with two worked problems and the labelling marks examiners actually award.
