| Abstract: | In this article,we deduced the period formula of simple pendulum in any oscillation angle,and further used three-point interpolation method of parabola to simplify this formula,to obtain the approximate formula of simple pendulum period.Its maximum value of relative error is smaller than 0.7%,which is more practical. |
