Symbol δ(x). A type of function that has the value zero except at the origin where it is infinite, with the integral of this function having the value 1. The delta function is not well defined in terms of simple function theory but it can be justified in a mathematically rigorous way. The function is used in mathematical physics to represent concepts such as point charges and impulsive forces.
