i'm interested in the "slope" command. After pressing the help-key the calculator show the following syntax:
slope(Line| |Pnt| |Cplx,[Pnt| |Cplx])
How can i read the symbols | [ ? What means that? How can i use the command? The example in the Help-menu is not very instructive for me.

The square brackets [] just mean that entry is optional. The Where symbol | is available in the Catlg list in the Toolbox.

Quote:"||" in a syntax is not the Where function (nor absolute value); it means "OR". Example: row(Mtrx(A),Intg(n)||Interval(n1..n2)) means there are two options:
(1) row(Matrix, Integer)

o.k. thank you. it works also for me in cas. But for heaven's sake (or what the hell) do i know if i can use an app function only in home-view or only in cas-view or in both views? |
