Hello Everybody,

Please, do you have some smarter solutions to write a long formula like this?

I put inside the file my actual primarily range of know-how.
How to compact.sm (13 KiB) downloaded 24 time(s).

Do you expect some improved solutions embedded in the system?
For instance: one alone split of a line seems in my opinion as being not enough.

Thanks for your attention,
Ioan

I don't have SMath here at work (company policy), but the following technique should work. It works in Mathcad, which I do have at work.

Set the function equal to the sum of a four-element column vector, then split the function definition at the three plus signs that separate the major elements of the definition and drop these pieces into the column vector. Please pardon any typos on my part.

The undocumented maple(op) has hidden virtue of simplifying.
Works fine your long formula ... 4th option.

Hi NotRetiredYet, Greetings from an AllreadyRetired,

Thank your for your suggestion. It's simplier and it works good:

Best Regards,
Ioan

Bonjour Jean,

Thank you for your proposal. Of course it could be seen as a forth solution.
As I see, Maple turns a little bit the terms but finally we heve always a sum of four main terms.

Merci encore,
Ioan

A great application of maple(op)
Suppose you have a long Lagrange canonical polynomial,
generously furbished of 15 D coefficients.
Tedious to collect all the coefficients by hand.
Click/click/done maple(op(Poly(x)))
Don't expand symbolic expr(x):=maple(op(Poly(x)))
... below expansion, set x:=1
evaluate the expansion ... all coefficients collected in vector.
Take care Ioan ... Jean.
