Lesson: 3.5 Rewriting Trig Expressions
Goal: Use trig identities to write equivalent trig expressions.
Our first step, for all of these problems, is to use trig identities (usually the tangent
identities, reciprocal identities, and Pythagorean identities) to rewrite the expression
in terms of
and
. Then, we will simplify as much as we can.
Examples
