Trigonometric function is an important function in Mathematics, it is closely linked with other mathematical knowledge, and there is often a wide range of applications in the study and research of other mathematical knowledge. In the study of trigonometric function, method for the best values of trigonometric function plays an important role. The cor-rect thinking method in calculating the trigonometric function most value is meaningful to learn the knowledge of the tri-gonometric function.
