# Naming Conventions

Mathematical functions in *Mathematica* are given names according to definite rules. As with most *Mathematica* functions, the names are usually complete English words, fully spelled out. For a few very common functions, *Mathematica* uses the traditional abbreviations. Thus the modulo function, for example, is Mod, not .

Mathematical functions that are usually referred to by a person's name have names in *Mathematica* of the form *PersonSymbol*. Thus, for example, the Legendre polynomials are denoted LegendreP[n, x]. Although this convention does lead to longer function names, it avoids any ambiguity or confusion.

When the standard notation for a mathematical function involves both subscripts and superscripts, the subscripts are given *before* the superscripts in the *Mathematica* form. Thus, for example, the associated Legendre polynomials are denoted LegendreP[n, m, x].
