A Cycloid Demonstration Teaching Aid for Higher Mathematics Teaching

Abstract

The invention belongs to the technical field of teaching tools, specifically a cycloid demonstration teaching aid for higher mathematics teaching, comprising an outer frame; a sliding cavity is opened in the outer frame, and sliding supports are arranged on the tops of both ends of the outer frame; A first fixed suction cup and a second fixed suction cup are slidably plugged into the seat; the bottom end of the first fixed suction cup is connected to a rotating column through bearing rotation, and a spiral groove is opened on the rotating column; rolling beads are arranged on the top of the outer frame, and The rolling ball and the spiral groove rotate and cooperate; the top of the rotating rod is provided with a rotating disk, and a U-shaped chalk holder is arranged on the rotating disk, and a chalk engaging unit is arranged in the U-shaped chalk holder; through the first fixed suction cup and the second fixed suction cup provided Not only the outer frame is fixed to prevent the chalk from demonstrating the cycloid, but the direction of the cycloid is shifted due to the shaking of the outer frame; the rotating disk can rotate and move horizontally on the surface of the blackboard, so that the chalk can draw clearly Out of the cycloid needed for teaching.

Description

technical field [0001] The invention belongs to the technical field of teaching tools, in particular to a cycloid demonstration teaching tool for advanced mathematics teaching. Background technique [0002] The equation of motion of an object in physics is a parameter equation in mathematics. Parametric equations are of great significance for solving practical problems. Cycloids are a very important class of curves, which can be divided into three categories: level cycloids, circular cycloids, and involutes. Most of our common curves can be regarded as special cases of cycloids, such as star line, heart line, Archimedes spiral, rose line and so on. Cycloids are also a useful class of curves, such as the steepest descent line is the level cycloid. [0003] The cycloid is one of the many fascinating curves in mathematics. It is defined as follows: a circle slowly rolls along a straight line, and the trajectory passed by a fixed point on the circle is called a cycloid. Spec...

Problems solved by technology

[0005] In order to make up for the deficiencies in the prior art, the present invention proposes a cycloid demonstration teaching aid for advanced mathematics teaching. The present invention is mainly used to solve the problem that the existing teaching aids are not clear due to the instability of the fixation, and the cycloid is easy to appear. The cycloid of the demonstration is deflected or slipped, which will affect the demonstration effect of the cycloid
