The Pendulum Swings Back

Robert F. Brown

Chapter Chapter 13 in A Topological Introduction to Nonlinear Analysis, 2014, pp 93-100 from Springer

Abstract: Abstract In the previous chapter, we returned to the equation of the forced pendulum y ″ + a sin y = e , $$\displaystyle{y'' + a\sin y = e,}$$ assuming now that the forcing term e: R → R is a continuous T-periodic function, but not necessarily an odd function as it was in Chap. 5. Recall that a = g ℓ $$a = \frac{g} {\ell}$$ where g is the gravitational constant and ℓ is the length of the pendulum, and therefore a > 0.
