Differential operator

In mathematics (particularly in differential calculus), a differential operator is an operator that takes a function as input, and returns a function as a result. Differential operators will differentiate the function in one or more variables. Probably the best known differential operator is differentiation itself, which is commonly written using  (in Leibniz's notation) and  (in Euler's notation).
