Consider a simple forced pendulum. The motion of the pendulum is governed by the following 2^nd order ordinary differential equation (ODE). The parameters L and g are specified below. a) Solve the following ODE using MATLAB's ODE Toolbox and plot theta vs. t for a time window of [0 15] b) The following ODE has an additional friction term on the right hand side of the ODE. Solve the ODE using MATLAB's ODE Toolbox and plot theta vs. t for a time window of [0 15]
