This required students to set up two parametric equations, use the dot product to establish two simultaneous equations, and solve. It wasn't enough to know the formula; you had to derive the geometry. Furthermore, the final part asked for the that is also parallel to a given vector—a higher-order synthesis of the vector chapter. : Keep your primary logic flow on the
