Complex and Parametric Motion Lesson Set
Use the complex-and-parametric topic page, the authored starter track, one parametric-motion checkpoint, and the vectors topic page so the plane-based math branch stays compact and teacher-usable.
This lesson set is for the moment when the math shelf should widen beyond graph transformations without losing the product's compact bench language. It starts with the complex-and-parametric topic page for orientation, uses the authored starter track for the main order, closes with the parametric-motion checkpoint already shipped inside that track, and then points to the vectors topic page so the next branch stays visible.
