👉 Dirac's delta function, named after Paul Dirac, is a mathematical function that represents an infinitesimal amount of a quantity. It has the property that it can be used to represent the difference between two values for a given quantity without actually changing them. The Dirac delta function is defined as: δ(x) = 0 if x=0 δ(x) = ∞ if x≠0 Where δ(x) represents the Dirac delta function, and it is often used in
