Lecture: Proving the Cyclic Chain Rule Using Geometry (5 minutes)

  • It would be useful for this lecture to have a 3D model of a graph, though it is not absolutely necessary
  • Show that the tangent plane to any given point will cross the x, y, and z axes at given points
  • Geometrically it can be shown by using the slope of each line between the three points that the cyclic chain rule is accurate
