MATSEC AM Pure Mathematics Complete Prep Course — Lesson 69: Tangents and normals

Sarah Mitchell teaches how to find tangent and normal equations at a point on a curve for MATSEC Advanced Matriculation Pure Mathematics. She covers differentiating first then substituting, the minus one over m rule for normals, the point-gradient straight-line form, the worked case of y equals x squared at x equals three giving y equals six x minus nine, horizontal and vertical special cases, implicit and parametric curves, and follow-up questions about axis intercepts and second intersections.
