AMRANI, D; PARADIS, P  e  BEAUDIN, M. Approximation expressions for the large-angle period of a simple pendulum revisited. Rev. mex. fís. E [online]. 2008, vol.54, n.1, pp.59-64. ISSN 1870-3542.

This paper presents the experimental accuracy performance of each of the approximation expressions relative to the exact period for large amplitudes of a simple pendulum in the interval 0° < θ < 180°. The plots of the linearized exact period as a function of linearized formulae were carried out and relative errors in these expressions were investigated. In addition, this paper gives a clear idea how each formula approximates the exact period
