Geometric Algebra Practice: Using GA identities to Demonstrate Equivalence of Rotation Formulas

Because newcomers to GA may have difficulty applying its identities to real problems, we use those identities to prove the equivalence of two expressions for rotations of a vector. Rather than simply present the proof, we first review the relevant GA identities, then formulate and explore reasonable conjectures that lead, promptly, to a solution.
