Question:How do I obtain a pde solution in real variables?

Dear all

When requesting Maple to solve, for example, the 2D Laplace equation the default solution is

U(x, y) = _F1(y-I*x)+_F2(y+I*x)

How can I ask Maple to provide a solution in real variables? I've tried "assuming U(x,y) real", but the result is the same.

Thank you very much for your help.
