The Pendulum Swings Back

  • Robert F. Brown


In the previous chapter, we returned to the equation of the forced pendulum
$$ y'' + a \sin y = e, $$
assuming now that the forcing term e: RR is a continuous T-periodic function, but not necessarily an odd function as it was in Chapter 5. It will be convenient to remember that \( a = \tfrac{g} {\ell } \) where g is the gravitational constant and l is the length of the pendulum, and therefore a > 0.
