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.

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 simplied symbolic format. For example:
320 returns 17.88854382 in Home view, and 8*√5 in the CAS.
