| Abstract: | Using the basic characteristic of spatial line's ecumenical equation and the basic theorem of a system of linear equation,the vector expression of spatial line was given.Using the vectors expression of spatial line and combine the geometric explanation of vector orthogonal or the method of the function of one variable,two simple methods of solving the distance from a point to a spatial line were presented. |
