In this paper, we present an efficient graphical method for solving differential equations known as Simulink. The method is fast, simple and offers us the opportunity to spend more time exploring the behaviour of the solutions rather than in solving the differential equation as it is often the case with analytical and numerical methods. The differential equation is represented by means of a model diagram which comprises of three sections namely: the input, computational and output sections. A convenient approach in which the model diagram is drawn using the differential equation parameters instead of their values is considered. Three approaches for drawing the computational section of the model diagram namely; the differential equation approach, state-space approach and transfer function approach are studied. The steps followed starting from drawing the model diagram; simulation and display of the solutions are outlined. Ways of creating simulation values in the MATLAB workspace for further use and analysis are discussed. As an illustration, a mass-spring system equation driven by a sinusoidal force is solved using Simulink. Numerical results obtained are given
