Suppose that at t = 0 rod’s temperature is a constant T0for 0 ≤ x ≤ 1, and that for t > 0 the left end is kept at temperature T0 and the right at 0. Thusthe boundary conditions can be stated as T(0, t) = T0, T(1, t) = 0 for t > 0 and initial conditionsT(x, 0) = T0 , 0 < x < 1.(a) Sketch the variation of the solution at the initial time and two later time, highlighting thephysical behaviour of the system. [Ans: Sketch the initial condition, the late time steady linearsolution ,and a curve showing the solution at a time 0
