Solve the Fisher's reaction diffusion equation etc..

Consider the Fisher's reactiondiffusion equation at = um+au(1u), 0 0, where u : 'u,(:1:,t), a > 0, subject to the boundary conditions u(0, t) : u(1, t) = 0 and initial conditions u(:r:,0) = sinfrzc;0 5 :1: 5 1. Design an 0(h2 + 82) nitedifference method for solving the equation (where h > 0 and E > 0 are spacestep and time
