Question
**Problem 2: Domain of Dependence and Region of Influence of a PDE** Consider the task of identifying and sketching the triangular domain of dependence and region of influence for the following partial differential equations (PDEs) at specified points. **(a)** For the equation \( u_{tt} = 4u_{xx} \) at the point \((x_1, t_1) = (5, 4)\). **(b)** For the equation \( u_{tt} = 3u_{xx} \) at the point \((x_1, t_1) = (0, 5)\). The goal is to graphically determine the regions influenced by past or future solutions of these PDEs at the given points.
