Luc has Mathcad 11 with other symbolic engine.

Sure:

Success!

P.S. Note that Mathcad 11 (symbolic engine: Maple) will give generally a single answer, even if multiple/periodic answers exist.

The example of Valery shows that Mathcad 15 (symbolic engine: Mupad) may give the multiple/periodic answer to such problems.

Mathcad 15
