Determination of a Point above or under A Curve

给出了平面上任意一点在一条曲线的上方和下方的判定条件,并利用得出的条件部分地讨论了曲线划分平面的问题.

This paper gives conditions to determine whether a point is above or under a given curve, and by employing the condition, partially discusses the problem that a given curve divides the R^2 plane into two parts.
