Abstract: By using the method of linear interpolation,an approximate period formula of a simple pendulum is derived. Through the comparison with the accurate formula gotten by Mathematica and other formulae described in different journals, this formula proves to be fairly precise.

Key words: simple pendulum harmonic vibration, period, Mathematica
