Problems solved by technology

In the prior art, when teaching advanced mathematics, it is mostly necessary to draw straight lines, cross lines, oblique lines, etc. on the blackboard, and most of the dimensions are drawn after measuring with a set square, ruler, angle ruler, etc., which is cumbersome and inefficient. Long teaching time, therefore, there is room for improvement

Abstract

The invention discloses a cycloid demonstration teaching aid for advanced mathematical teaching and a use method. The teaching aid comprises a Y ruler, an X ruler, laser lamps, lenses, lamp switches and rotating shafts, wherein one end of the Y ruler and one end of the X ruler are connected by 90 degrees; the laser lamps are uniformly arranged at the Y ruler and the X ruler; the lenses are arranged at the front ends of the laser lamps; the rotating shafts are arranged at the rear ends of the laser lamps; the laser lamps are rotationally connected with the Y ruler or the X ruler through the rotating shafts; and the lamp switches are arranged on the laser lamps. Compared with the prior art, a plurality of straight lines, diagonal lines and intersecting lines can be arbitrarily transmitted ona blackboard through the laser lamps, and the angle of each line can be adjusted arbitrarily, so that the advanced mathematical teaching is facilitated, the drawing time is shortened, the teaching efficiency is improved, and the teaching aid has popularization and application values.

Description

technical field [0001] The invention relates to a teaching auxiliary device, in particular to a cycloid demonstration teaching aid for advanced mathematics teaching and a use method thereof. Background technique [0002] Advanced mathematics refers to the more complicated part of mathematics objects and methods compared with elementary mathematics. Broadly speaking, mathematics other than elementary mathematics is advanced mathematics, and there are also those who refer to the more in-depth algebra, geometry, and simple set theory and logic in middle school as secondary mathematics, and regard them as elementary mathematics in primary and secondary schools and university mathematics. Phase transition to higher mathematics. In the prior art, when teaching advanced mathematics, it is mostly necessary to draw straight lines, cross lines, oblique lines, etc. on the blackboard, and most of the dimensions are drawn after measuring with a set square, ruler, angle ruler, etc., whic...
