Secant pythagorean identity
WebPythagorean identities are important identities in trigonometry that are derived from the Pythagoras theorem. These identities are used in solving many trigonometric problems … Web7 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 ...
