MATSEC AM Pure Mathematics Complete Prep Course — Lesson 71: Optimisation in practical problems

Sarah Mitchell teaches the six-step optimisation method for MATSEC Paper One differentiation questions, from naming variables to justifying the turning point. She works the forty-metre fencing problem against a wall, reaching ten by twenty metres and two hundred square metres, then minimises the surface area of a closed box of volume eight cubic metres, landing on a two-metre cube with twenty-four square metres.
