%proving one_as_scalar_mult_id

With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of
one_as_scalar_mult_id:
(see dependencies)

one_as_scalar_mult_id may now be readily provable (assuming required theorems are usable).  Simply execute "%qed".
