Solving Trigonometric Equations with Trig Identities.

Honors Pre Calculus, Mr. Erlin explains how to solve Trig Equations using Trig identities (Sum/Difference, Double Angle, Pythagorean Id, Quotient Id, Reciprocal Id, etc.). We also speak about some legacy solving issues from Advanced Algebra, like difference of squares, squaring to solve, factoring and using zero product property.
