Use Matlab pdetool to solve this problem numerically and provide the solution in a 3-D graph. Solution. We assume that u(x,t) can be separated into X(x), a function of x alone, and Y(y), a function of y alone. u(x,t) = X(x) Y(y) From the following relations = T ( = T = T ( = T. The original PDE becomes = 0 Divide the above equation by XY to obtain PARTIAL DIFFERENTIAL EQuATIONS (40 POINTS) Use the MATLAB function pdepe to solve the following boundary value problem a(t, 0) = 0, a(t, 1)=0, u(0, z) =-x2 + x. The output of your file should be the plot of the solution ( 0,1). Solution The problem is regular since it is posed on a nite interval 1 x e and the coe cient function p(x) = x2 is smooth and nonzero on the interval (including at the endpoints). Any eigenvalue is real and positive (e.g. from the Rayleigh quotient, since p>0 and q= 0). The equation is a homogeneous Euler equation, so we look for solutions
