A Realization Method of Dynamic Geometry Multi-Coordinate System

Abstract

The invention discloses a method for realizing a dynamic geometric multi-coordinate system, which comprises the following steps: S1, determining the dynamic variables of the dynamic geometric image; S2, extracting the dynamic variables to form a sequence of feature vectors; S3, selecting the origin of the multi-coordinate system in the feature vector space ; S4. According to the metric relationship between each feature vector and the origin of each coordinate system, map the sequence of feature vectors in each coordinate system to form multiple coordinate systems. Multiple coordinate systems can be realized to represent dynamic geometric figures, so that students can more clearly understand the changing process of dynamic geometric figures from many aspects, improve students' interest in problem-solving and problem-solving efficiency, and expand students' thinking.

Description

technical field

[0001] The invention relates to a method for realizing a multi-coordinate system, in particular to a method for realizing a dynamic geometry multi-coordinate system. Background technique

[0002] With the development of science and technology, education and teaching are constantly improving. Now teaching is no longer limited to teachers explaining to students by drawing pictures on the blackboard. More and more teaching software (such as backgammon reading machine, backgammon tutoring machine) ) can realize drawing on computer and mobile Ipad.

[0003] However, there is only one coordinate system in the existing drawing software, and the graphics are also formed in this coordinate system. However, with the deepening of the complexity of the graphics, it is difficult to meet the needs of a single coordinate system for dynamic geometric graphics. Therefore, how to implement multiple coordinate systems to represent graphics is a problem that needs to be solved ...
