The notebook provides the solutions to two heat conduction problems where the thermal conductivity varies with temperature. The author starts by using the shooting technique and NDSolve to get the exact numerical solutions to the nonlinear boundary value problems. The governing equation is derived using the Boltzmann transformation. Then, the method of successive approximations, described in M. N. Özisik, Heat Conduction, Wiley, New York, 1980, is used to obtain the same solutions. Convergence of this method is achieved after only two iterations.
