Using mathematical functions
Math functions
The HP 40gs contains many math functions. The functions
are grouped in categories. For example, the Matrix
category contains functions for manipulating matrices.
The Probability category (shown as
Prob. on the MATH
menu) contains functions for working with probability.
To use a math function in HOME view, you enter the
function onto the command line, and include the
arguments in parentheses after the function. You can also
select a math function from the MATH menu.
Note that this chapter covers only the use of mathematical
functions in HOME view. The use of mathematical
functions in CAS is described in Chapter14, “Computer
Algebra System (CAS)”.
The MATH menu
The MATH menu provides access to math functions,
physical constants, and programming constants. You can
also access CAS commands.
The MATH menu is organized by category. For each
category of functions on the left, there is a list of function
names on the right. The highlighted category is the
current category.
• When you press , you see the menu list of
Math categories in the left column and the
corresponding functions of the highlighted category
in the right column. The menu key
indicates
that the MATH FUNCTIONS menu list is active.
