Canonical form
From Wikipedia, the free encyclopedia
Generally, in mathematics, a canonical form is a function that is written in the most standard, conventional, and logical way. For example, polynomials are usually written with the terms in descending powers: it is more usual to write x2 + x + 30 than x + 30 + x2, although the two forms are essentially equivalent.
A canonical form is required to have two essential properties. Every object under consideration must have exactly one canonical form, and two objects that have the same canonical form must be essentially the same.
