【Abstract】 In order to probe the meaning of parameter θ in ellipse parameter equation,the geometric meaning of parameters,which are in the parameter equation of ellipse and general polar coordinates,were found,then the geometric meaning of parameters,which are in the parameter equation for global and general spherical coordinates,were found also,when the three-dimensional space serve as a point of departure in considering in question.更多还原
