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.

Hi NotRetiredYet, Greetings from an AllreadyRetired,
Thank your for your suggestion. It's simplier and it works good:
Best Regards,
Ioan

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
