SUMMARY
The secular equation in normal mode analysis of coupled oscillators is defined by its association with long time periods, particularly in the context of perturbations in planetary motions. The term "secular" originates from its historical use to describe phenomena that occur over extended durations, contrasting with the sacred, which is timeless. In perturbation theory, secular terms emerge in higher-order solutions that address the order unity differential equation, highlighting their significance in analyzing long-term behaviors of systems.
