《几何画板》软件从5.0版本开始,在“度量”菜单中增加了一个新的命令“点的值”.为行文方便,以下简称点值.点值是刻画点在各种路径上相应位置的一个量,这个数值与路径上的点成一一对应关系,作为形的“点”和作为数的“值”结合在了一起,这种功能是数形结合思想在数学软件中的又一次应用.引入点值的概念,可以使用户能够用数来精确控制点在路径上的位置,轻松地解决以前版本中很难完成的问题.点值的概念源于《几何画板》缩放功能中的缩放比,但其意义又超越了以前版本中缩放比的概念,进行了拓展和延伸,有着更为深刻的意义.
“Geometry” software from the 5.0 version, in the “Measurement” menu has added a new command “dot value ” for the convenience of the text, hereinafter referred to as the point value. Point value is to describe the point in a variety of paths On the corresponding position of a quantity, this value and the path of the point in a one-to-one correspondence, as the shape of the “dot” and as the number of “value” combined together, this function is the number of combination of thinking Another application in maths software is the introduction of the concept of point values that allows users to precisely control the position of points on the path with numbers and easily solve problems that were difficult to accomplish in previous versions. Geometry "scaling function in the zoom ratio, but its meaning goes beyond the previous version of the concept of zoom ratio, carried out to expand and extend, has a more profound significance.
