Following are definitions for all categories of functions except
List, Matrix, and Statistics, each of which appears in its own
chapter. Except for the keyboard operations, which do not
appear in the MATH menu, all other functions are listed by
their category in the MATH menu.
Each function's definition includes its syntax, that is, the
exact order and spelling of a function's name, its delimiters
(punctuation), and its arguments. Note that the syntax for a
function does not require spaces.
