First-Order Partial Differential Equations the case of the first-order ODE discussed above. Clearly, this initial point does not have to be on the y axis. If the values of uΩx, yæ on the y axis between a1 í y í a2 are given, then the values of uΩx, yæ are known in the strip of the x-y plane with a1 í y í a2.
