Sign function: Properties in mathematical analysis, Generalizations & Some algebraic identities

In mathematics, the sign function or signum function (from signum, Latin for "sign") is a function that has the value −1, +1 or 0 according to whether the sign of a given real number is positive or negative, or the given number is itself zero. In mathematical notation the sign function is often represented as sgn ⁡ x {\displaystyle \operatorname {sgn} x}…
