1. First-order PDE examples. For each of the following problems find the char- acteristic lines, sketch some of them in the xy-plane, state the general solution to the PDE, and find the particular solution satisfying the boundary data. (a) 3ux +4uy = 0, u(x, 0) = sin(2x). (b) Ux+2uy = 0, u(0, y) = y. (c) √1 − x² Ux + Uy = 0, u(0, y) = y. Consider only the restricted domain |x| ≤ 1. (d) Ux+ Uy = 1, u = x on y = x/2.
