| Abstract: | By using of distance between two points and point to the straight-line, slope, geometry, planar vector gave the methodes of sloving most value of the complex trigonometric functions, one monadic function, multi function. These methods reflect the superiority and importance of gemetric model, and deepen student＇s undestanding of the connotation and extension of the geometry. |
