Solve:
(xy sin xy + cos xy)ydx + (xy sin xy - cos xy)xdy = 0
Starting from the equation of motion and after solving it show that for a forced oscillator in steady state the displacement amplitude is independent of natural frequency

A vibrating system of 2 gm mass is displaced from its mean position. If the restoring force
acting on the mass is 5 dyne /cm and the damping factor is 1.0 dyne/cm/s. Check if the motion
is oscillatory or not? If oscillatory, calculate the time period of oscillation. Calculate the Q
value and logarithmic decrement of the system.
