Dirac delta function
The Dirac delta function, named after Paul Dirac, is a mathematical concept that represents a distribution with a single point of infinite density. It is often used to model instantaneous events or point sources in various fields, including Physics, Engineering, and Signal processing. The Dirac delta function is defined as a function that is zero everywhere except at a single point, where it is infinite, and its integral over all space is equal to one. This function is useful for solving problems involving Differential equations and Integral equations. The Dirac delta function has numerous applications in Quantum mechanics, Electromagnetism, and Control theory.
