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.

"||" 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)
(2) row(Matrix, Interval)
Thanks for the correction.
O.k. but now i have the next problem: When i imput "slope(line(y=2*x-3))" the calculator shows an error message. why?
Have you tried it in CAS mode? it works for me.

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?
