Don't forget to drag S, or you'll miss it.
Rigid motion and constraints with parametric curves and vectors.
Slumberland's current approach:
Begin with physical problems involving motion.
Solve them geometrically.
Translate the geometric constructions to vectors.
Simplify.
If I need only the parametric equation, that is easy to get from the vectors. To retain additional elements of the physical problem, I can just back up to an earlier step.
