Functions and commands 307
RatFrac: a rational fraction
Fnc: a function
Var: a variable
LstVar: a list of variables
Parameters that are optional are given in square brackets, as
in
NORMAL_ICDF([,,]p).
For ease of reading, commas are used to separate
parameters, but these are only necessary to separate
parameters. Thus a single-parameter command needs no
comma after the parameter even if, in the syntax shown
below, there is a comma between it and an optional
parameter. An example is the syntax zeros(Expr,[Var]).
The comma is needed only if you are specifying the optional
parameter Var.
|| is used to indicate or. For example, in
DotDiv(Lst||Mtrx,Lst||Mtrx), the parameters can
be lists or matrices.
Keyboard functions
The most frequently used functions are available directly from
the keyboard. Many of the keyboard functions also accept
complex numbers as arguments. Enter the keys and inputs
shown below and press
E to evaluate the expression.
In the examples below, shifted functions are represented
by the actual keys to be pressed, with the function name
shown in parentheses. For example,
Se
(ASIN) means
that to make an arc sine calculation (ASIN), you press
Se
.
The examples below show the results you would get in Home
view. If you are in the CAS, the results are given in simplified
symbolic format. For example:
Sj
320 returns 17.88854382 in Home view, and
8*5 in the CAS.
