Trig 3.0. Students know the identity cos2(x) + sin2(x) = 1: 3.1. Students prove that this identity is equivalent to the Pythagorean theorem (i.e., students can prove this identity by using the Pythagorean theorem and, conversely, they can prove the Pythagorean theorem as a consequence of this identity…
