Abstract: We present an analytic and asymptotic solution of an unsteady laminar boundary layer of micropolar fluid flow past a moving wedge. Similarity transformations reduce the number of independent variables of partial differential equations in the governing system to a coupled system of ordinary differential equations. An exact solution obtained for particular values of parameters are extended to obtain an analytical solution for more general values of the parameters involved. Analytical results are consistent with the numerical results obtained by employing implicit finite difference method. The variations with position, material parameter and time, shown by Velocity, shear stress and gyration profiles obtained from both the solutions are analyzed.
