n mathematics, an identity is an equation that is always true. When you learned how to factor()2expressions and equations, you worked with several algebraic identities, including =22322 2 and( )= ( )( ). These identities helped you to rewriteand simplify more complex expressions or equations. This, in turn, allowed you to more easilysolve problems.In this module you were introduced to trigonometric identities, including reciprocal identities,quotient identities, Pythagorean identities, and others. Like algebraic identities, you can usetrigonometric identities to help you rewrite and simplify more complex expressions or equationsin order to more easily solve prob
