In espionage movies, we see international spies with multiple passports, each claiming a different identity. However, we know that each of those passports represents the same person. The trigonometric identities act in a similar manner to multiple passports—there are many ways to represent the same trigonometric expression. Just as a spy will choose an Italian passport when traveling to Italy, we choose the identity that applies to the given scenario when solving a trigonometric equation. In this section, we will examine how to use the fundamental trigonometric identities, to verify new identities and to simplify trigonometric expressions. You are asked to solve problems involving trigonometric identities in WeBWorK in the assignments titled "Chapter 7. Identities enable us to simplify complicated expressions.
