Discussion and analysis on the approximate formula for the period of a large-angle pendulum
A comprehensive analysis and discussion have been conducted on the approximate formula for the period of a large-angle pendulum in the literature.In terms of analytical form,the arithmetic-geometric mean recur-sive method is used.Although it has the highest accuracy,other simple approximate formulas can be selected when considering the convenience of calculation,simplicity of the formula,and the need for experimental measurement accuracy.
