为了从正函数的圖象中,得到反函数的几何圖形(在座标軸的正常情况下),可以使平面XOY繞第一和第三座标角的二等分線轉动180°(圖工和圖2).
In order to get the inverse function geometry from the image of the positive function (in the normal case of the coordinate axis), the plane XOY can be rotated 180° around the bisector of the first and third coordinate angles. And Figure 2).
