Standard physics textbooks simplify pendulum motion by assuming the swing angle is small ($\sin\theta \approx \theta$), which only works up to about $23^\circ$ (Crawford, \textit{Waves}). Because of this shortcut, textbooks claim a pendulum's swing time never changes with amplitude, its motion is purely sinusoidal, and two connected pendulums always trade energy completely back and...
