| Abstract: | This paper discusses the graphic problem of ellipse normal through a point outside the ellipse. Concluded are the unsolvability of geometric graphic method to solve this problem . According to the relationship between ellipse and its normal, the analytic equation of ellipse normal solution is built as well as the complicacy of analytic method. A geometric approach graphic method on this problem is advanced, and the graphic steps on this method are given. |
