WebFor the next trigonometric identities we start with Pythagoras' Theorem: The Pythagorean Theorem says that, in a right triangle, the square of a plus the square of b is equal to the square of c: a 2 + b 2 = c 2. Dividing through by c2 gives. a2 c2 + b2 c2 = c2 c2. This can be simplified to: ( a c )2 + ( b c )2 = 1. Web28 de mai. de 2024 · Here is a systematic way to produce a trigonometry proof: 1. Convert all cosecants, secants, cotangents, and tangents to expressions involving only sines and cosines. The first group of five identities on the above web page will allow you to do this easily. That will give you a "simpler" equation to prove. 2.
