Harmonic Force Excitation Steady State Amplitude and Phase Proof

The video tutorial explains how to derive the steady state amplitude and phase of a spring mass damper system with an external force. It introduces the use of complex numbers and algebra to solve the differential equation, linking the imaginary component of a complex solution to the real-world sinusoidal force. The tutorial simplifies the expression using trigonometry and highlights the importance of this method for more complex systems.
