Webb5 feb. 2024 · Verifying Trigonometric Identities Objective: To verify that two expressions are equivalent. That is, we want to verify that what we have is an identity. • To do this, we generally pick the expression on one side of the given identity and manipulate that expression until we get the other side. WebbNever write a trigonometric ratio without an angle. For example, \(\tan = \frac{\sin }{ \cos}\) has no meaning. For proving identities, only simplify one side of the identity at a time. As seen in the worked example above, sometimes both sides of the identity need to be simplified. Remember to write down restrictions:
