# The Deltafunction as the Limit of Some Special Functions

Requires a Wolfram Notebook System

Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.

Another Demonstration gives some representations for the Dirac deltafunction as the limit of elementary functions (see the related links below).This Demonstration illustrates several additional limiting relations involving special functions and the deltafunction:
