Functions
A function returns a value. For example, ÷, L, +, ‡(, and log( are the
functions in the example on the previous page. In general, the first letter of
each function is lowercase on the TI-83 Plus. Most functions take at least
one argument, as indicated by an open parenthesis ( ( ) following the
name. For example, sin( requires one argument, sin(value).
