Approximation for a large-angle simple pendulum period

Abstract: An approximation scheme to obtain the period for large amplitude oscillations of a simple pendulum is analysed and discussed. The analytical approximate formula for the period is the same as that suggested by Hite (2005 Phys. Teach. 43 290), but it is now obtained analytically by means of a term-by-term comparison of the power-series expansion for the approximate period with the corresponding series for the exact period.

“…The nonlinear differential equation for a simple pendulum can be solved exactly and the period and periodic solution expressions involve the complete elliptic integral of the first kind and the Jacobi elliptic functions, respectively [2,4,5]. For this reason, several approximation schemes have been developed to investigate the situation for large amplitude oscillations of a simple pendulum, and several approximations for its largeangle period have been proposed (a summary of most of them can be found in [3,[6][7][8][9][10]) that differ in complexity and domains of validity: some are intuitive, others use ingenuous strategies, while yet others are based on relatively sophisticated procedures [11]. These approximate expressions for the period of a simple pendulum may be obtained in three ways, and in some cases the same results are reached.…”

“…The leaf functions make it possible to derive a differential equation consisting of the term d 2 θ/dt 2 , the term dθ/dt, the term θ, and the term θ 3 /6, as shown in Eq. (8). However, comparing the ODE obtained from the leaf function in Eq.…”
