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.
22 Ιαν 2020 · Knowing the steps necessary to Verify (Prove) Trigonometric Identities, let's look at 15 classic examples of how to verify trig identities step-by-step.
Example \(\PageIndex{1}\): Verifying a Trigonometric Identity. To verify that equation (1) is an identity, we work with the expression \(\tan^{2}(x) + 1\). It can often be a good idea to write all of the trigonometric functions in terms of the cosine and sine to start.
Verify the fundamental trigonometric identities. Identities enable us to simplify complicated expressions. They are the basic tools of trigonometry used in solving trigonometric equations, just as factoring, finding common denominators, and using special formulas are the basic tools of solving algebraic equations.
