## Delta Function -- from Wolfram MathWorld

Delta Function. The delta function is a generalized function that can be defined as the limit of a class of delta sequences.The delta function is sometimes called "Dirac's delta function" or the "impulse symbol" (Bracewell 1999).

This article describes the formula syntax and usage of the DELTA function in Microsoft Excel. Description. Tests whether two values are equal. Returns 1 if number1 = number2; returns 0 otherwise. Use this function to filter a set of values. For example, by summing several DELTA functions you calculate the count of equal pairs.

## Differential Equations - Dirac Delta Function

In this section we introduce the Dirac Delta function and derive the Laplace transform of the Dirac Delta function. We work a couple of examples of solving differential equations involving Dirac Delta functions and unlike problems with Heaviside functions our only real option for this kind of differential equation is to use Laplace transforms.
