Is it possible to define complex terms of an equation as letters or
such like instead of entering the terms directly into the equation, eg.
if I had an equation such as y=sqrt(D(D-2.Jq), where Jq= some other
equation such as Jq=4.((J.cos(pi.x))+(J'.Kq.cos(2.pi.x))), could I define
Jq somewhere instead of having to input it directly? I believe they have
such a system in Kalidagraph. If so, how many levels may you have, could
you then define Kq in such a manner and have a term within a term within
an equation? PS I wouldn't study the equations above too intently, as they serve only
as examples, not as real equations.
Any help would be greatly appreciated.
