hi friends am using maple 13 which is unable to find exact solutions for pdes
because for exact solution i should have maple 15 but am not able to install that so please can anyone of u can find exact sloution for me of the pde
pde := diff(U(x, y), x, x)-3*(diff(U(x, y), y, y))+16 = 0 where boundary conditions are
U=0 on x=1,-1
U=0 on x=1,-1
diff(U(x, y), y) = -U on y=1, -1< x
diff(U(x, y), y) = U on y=-1, -1< x
