Examples of these special functions are shown here using both the ALG and
RPN modes. As an exercise, verify that
GAMMA(2.3) = 1.166711…,
PSI(1.5,3) = 1.40909..,
and
Psi(1.5) = 3.64899739..E-2
.
These calculations are shown in the following screen shot:
Calculator constants
The following are the mathematical constants used by your calculator:
•
e
:
the base of natural logarithms.
•
i
:
the imaginary unit,
i
i 2
= -1.
•
π
:
the ratio of the length of the circle to its diameter.
•
MINR: the minimum real number available to the calculator.
•
MAXR: the maximum real number available to the calculator.
To have access to these constants, select option
11. CONSTANTS..
in the
MTH
menu,
The constants are listed as follows:
Selecting any of these entries will place the value selected, whether a symbol
(e.g.,
e
,
i
,
π
,
MINR
, or
MAXR
) or a value (
2.71.., (0,1), 3.14.., 1E-499,
9.99..E499
) in the stack.
