* The random number you generate might be different.
** Angles can be computed in degrees or radians. Examples show angles in
degrees. (See: Choosing the Angle Units).
Universal Power ;
Press ; to raise the displayed
postive number to any power (for example, 2
-5
or 2
(1/3)
.)
Note: Because the reciprocal of an even number (such as, 1/2, 1/4, 1/6) is a
complex number, you can only raise a negative number to an integer power or
the reciprocal of an odd number.
Parentheses 9 :
Use parentheses to control the order in which the calculator evaluates a
numeric expression in division, multiplication, powers, roots, and logarithm
calculations. The calculator includes up to 15 levels of parentheses and up to 8
pending operations.
Note: You do not have to press : for expressions ending in a series of closed
parentheses. Pressing N closes parentheses automatically, evaluates the
expression, and displays the final result. To view intermediate results, press :
once for each open parenthesis.
Factorial & g
The number for which you compute a factorial must be a positive integer less
than or equal to 69.
Random Numbers & a
The calculator generates a random real number between zero and one
(0<x<1) from a uniform distribution.
You can repeat a sequence of random numbers by storing a
seed value in the
random number generator. Seed values help you recreate experiments by
generating the same series of random numbers.
To store a seed value, key in an integer greater than zero and press
D & a.
