172 6_1_4 Verifying Trig Identities (Short exercise in factoring) M2U00417.mp4
A horrible, mean, and awful identity exercise handled in short order when we utilize factoring by grouping. A reminder that most of the problems in this section are caused by algebraic difficulties, not by trig functions. 8:23 © 2008 by Raymond E. Griffith.
