In this work, the homotopy analysis method is applied to study the unsteady
boundary-layer flow and heat transfer due to a stretching sheet. The analytic solutions of
the system of nonlinear ordinary differential equations are constructed in the series form.
The convergence of the obtained series solutions is carefully analyzed. The velocity
and temperature profiles are shown and the influence of non-dimensional parameter on
the heat transfer is
