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 .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 .
