Use finite difference - explicit method to
²/x² + delu/delx = delu/delt
Over 0 ≤ x ≤ 1 and 0 ≤ ≤ 3, given the boundary conditions the combination of initial conditions (0,) = 0 andu(1 .) = 0 the initial conditions u(x, 0) = 0, b = - 4, ,x = 0.2, and = 0.5 . onditions and boundary conditions will give you an unusual cace how willyou solve it
