5. Consider a diffusion problem on the interval 0 < x < 1 governed by the pde ut = uxx. Assume that the solution satisfies the boundary conditions u(0) = 0.5 and u′(1) = −3(u(1) − 0.7). Find the steady state solution v(x) for this problem. Hint: The steady state solution must satisfy the pde and the boundary conditions.
