Verifying the identities illustrates how expressions can be rewritten to simplify a problem. Simplifying one side of the equation to equal the other side is a method for verifying an identity. See Example and Example . The approach to verifying an identity depends on the nature of ... Webb7 sep. 2015 · 1 + tan2x = sec2x. This can be derived from the standard Pythagorean identity by dividing everything by cos2x, like so: cos2x + sin2x = 1. cos2x cos2x + sin2x cos2x = 1 cos2x. 1 + tan2x = sec2x. From this identity, we can rearrange the terms to arrive at the answer to your question. tan2x = sec2x −1. It would help you in the future to know ... highland homes builder ceiling fans
