Question: 1. Let u = u (x, y), t = r cos (0 ) , y 02r 2. Consider u = u(x, y) with e Fur

1. Let u = u (x, y), t = r cos (0 ) , y 02r 2. Consider u = u(x, y) with e Fur + Wy = 0. Using a suitable change of variables, find the general solution to the above PDE. If the initial condition is given by u(x, 0) = (x), then find the particular solution u(x, y)
