Consider the 1-dimensional heat equation with a source term (f(x, t)) a2u = a- + f(x, t). at a.x2 (1) Discretize the equation using forward-difference in time and central difference in space. Determine the order of convergence and the stability condition for the scheme obtained. Comment on the convergence of the scheme.
