An analytical model is developed for the effect of cooling a slab under continuously varying boundary conditions of exponential character. An exact and explicit solution is derived for the temperature distribution over the entire slab. The solution is obtained by solving an appropriate functional equation in the complex plane. This equation has the form of a difference equation.
