To VERIFY AN IDENTITY: Work on each side separately and make sure you don’t move things from one side to the other! You can work on both sides at the same time – but you just can’t move things from one side to the other. Verify the identity. Example 1: sin𝜃cot𝜃sec𝜃=1 Example 2: 1−2sin2𝜃=2cos2𝜃−1 Example 3: Factor a.

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.
