Suppose that =A, A2 are constants such that u(x, y) = F(x + 2y) statisfied the PDE for any twice-differentiable function of one variable F(s). 24 ( 32 u (x, y)) - 10 ( 3x u (x, y)) + +3 2 u (x, y) = 0 Suppose also that 2, enter the values of A, A2 in the boxes below. A1 = 22 = Hence the soution will be of the form Solve the PDE with the initial conditions u(x, y) = (x + 21y) + (x + y). u (x, 0) = 6 sin (x), uy (x, 0) = 0. Enter the expression for u(x, y) in the box below using Maple syntax. u(x, y) = Note: the expression should be in terms of x and y, but not 1, 2.
