(a) Use the method of characteristics to solve the following boundary-value problem: y³ux (x, y) + uy (x, y) = 0, 0 < x, y ER, u(0, y) = 8y, y R for the function u(x, y). (b) Verify that the solution you found in part (a) solves the partial differential equa- tion and the boundary condition. (c) Sketch and label a representative sample of the characteristic curves in part (a) and explain how this shows that the method of characteristics gives us a solution to the boundary-value problem in part (a) for all points (x, y) = R2 where x ≥ 0. ha mort nana 5
