Consider the PDE (4) uyy + x2 uy = 0. a) Find the general solution. b) Verify that your solution solves the DE. c) Try to solve the boundary value problems consisting of the given equation and the following boundary conditions. In each case state if there is a unique solution, infinitely many solutions, or no solution. i) u(x, 0) = x2 , ii) u(x, 0) = x2 , iii) u(x, 0) = x2 , uy (0, y ) = y uy (x, y ) |y=x = ex uy (1, y ) = e2y 8. Solve the PDE 2 u x + uy + u = 0 subject to the initial condition u(x, 0) = cos x. 9. Solve the initial value problem 3 y 2 ux on the domain y 0. xuy = x, u(x, 0) = e x...
