value of point “点的值”,这本该说成ratio,就是因为创造了“点的值”这个名词,19楼的Jan,
以为”点的值“是点到曲线的距离。几何画板中的原文就没有点的值这个说法,原文就是ratio---比。作者: inRm 时间: 2012-8-24 11:00
“点的值”系由"value of point”汉化而来,跟ratio是两个概念作者: myzam 时间: 2012-8-24 11:09

e.g they mean split point from segment and merge point to curve.
1.Draw a segment AB.
2.Draw point C,C is moved point on segment AB.
3.Measure ratio of point A,B,C,set k=AC/AB.
4.Plot y=x^2,mark for m.
5.Split point C from segment AB.
6.Merge point C to curve m,ok.
tip:
value of point (点的值)is meaning of the ratio.Here is invented,ha,ha.
