Examples for
Mathematical Functions
In mathematics, a function is defined as a relation, numerical or symbolic, between a set of inputs (known as the function's domain) and a set of potential outputs (the function's codomain). The power of the Wolfram Language enables Wolfram|Alpha to compute properties both for generic functional forms input by the user and for hundreds of known special functions. Use our broad base of functionality to compute properties like periodicity, injectivity, parity, etc. for polynomial, elementary and other special functions.
