Ex … WebThis page covers Pythagorean identities. The identity: sin²x + cos²x = 1 can be used to derive two more important identities: By dividing each of these terms by sin²x, we can derive a second identity: 1 + cot²x = cosec²x By dividing (*) by cos²x, we arrive at the third (and final) identity: tan²x + 1 = sec²x
