RatFrac: a rational fraction
Val: a real value
Var: a variable
Parameters that are optional are given in square brackets, as in NORMAL_ICDF([μ,σ,]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.
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
to evaluate the expression.
NOTE: In the examples below, shifted functions are represented by the actual keys to be pressed, with the
function name shown in parentheses. For example, (ASIN) means that to make an arc sine
calculation (ASIN), you press .
The examples below show the results you would get in Home view. If you are in the CAS, the results are given
in simplied symbolic format. For example:
320 returns 17.88854382 in Home view, and 8*√5 in the CAS.
Add, subtract, multiply, divide. Also accepts complex numbers, lists, and matrices.
value1 + value2, etc
Natural logarithm. Also accepts complex numbers.

Example:
LN(1) returns 0
