Question: 25.18 The following is an initial value, second-order differential equation: d'x dx + (5x) + (x+7) sin(wt) = 0 dr dt where dx (0)

25.18 The following is an initial value, second-order differential equation: d'x dx

25.18 The following is an initial value, second-order differential equation: d'x dx + (5x) + (x+7) sin(wt) = 0 dr dt where dx (0) = 1.5 and x(0) = 6 dt 1. Decompose the equation into two first-order dif- Note that w = ferential equations. After the decomposition, solve the system from t= 0 to 15 and plot the results. %3D Use 4th Order Runge-Kutta method. Use h=1 and go from t = 0 to t = 2. %3D Only solve from t=0 to t=2 instead of from t=0 to t=15. h = deltat = 1. Use the Runge-Kutta 4th order method to solve. %3D %3D
