PDE, laplace, exact, should be simple...

forgive the simplicity of this:

D[u[x, y], {x, 2}] + D[u[x, y], {y, 2}] == 0


BCs={u[0, y] == 0, u[x, 0] == 0, u[1, y] == 0, u[x, 1] ===
 Sin[=F0 x]}


DSolve etc, etc, etc...


A solution is Sin[Pi x] Sinh[Pi y]


How can I get mathematica to come up with this gem ?


thanks, and sorry again for any stupidity on my part
