the number determine the display format.

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-84 Plus. Most functions take at least one argument, as indicated by an open
parenthesis (() following the n ame. For example, sin( requires one argument, sin(value).

An instruction initiates an action. For example, ClrDraw is an instruction that clears any
drawn elements from a graph. Instructions cannot be used in expressions. In general,
the first letter of each instruction name is uppercase. Some instructions take more than
one argument, as indicated by an open parenthesis (() at the end of the name. For
example, Circle( requires three arguments, Circle(X,Y,radius).
