In mathematics an iden.y is an equality relation A = B, such that A and B contain some variables and A and B produce the same value as each other regardless of what values usually numbers are subs.uted for the variables. In other words, A = B is an iden.y if A and B define the same functions.. - Reciprocal iden.ies. displaymath161. Pythagorean Iden.ies. displaymath162. Quotient Iden.ies. displaymath163.

Power-Reducing/Half Angle .In mathematics, an "iden.y" is an equation which is always true. These can be "trivially" true, like "x = x" or usefully true, such as the Pythagorean Theorem 's "a2 + b2 = c2" for right triangles. There are loads of tr.nometric iden.ies, but the following are the ones you 're most likely to see and use..
