Consider a single degree of freedom system, the equation of motion of the system is describe as such
mx"+cx'+k*sin(omega_t)x=Fsin(omega_t)
where m=10kg c=20Ns/m k=10kN/m omega=20rad/s
Which of the ODE solver should I use to solve the equation above? How can I produce a time history profile of the motion?
