Chapter 3: Math, Calculus, and Test Operations
The A to Z Reference details
which data types are valid
arguments for each function.
The most common
mathematical functions are
on the TI-86 keyboard. For
syntax, details, and examples
of these functions, refer to
the A to Z Reference.

x (the multiplicative inverse)
is equivalent to the
reciprocal, 1àx.

Keyboard Mathematical Functions

You can use these mathematical functions in expressions with real or complex values. You
can use some of them with lists, vectors, matrices, or strings.
When you use lists, vectors, or matrices, the valid functions return a list of results calculated
on an element-by-element basis. If you use two lists, vectors, or matrices in the same
expression, they must be equal in dimension.
