Problems solved by technology

[0002] When explaining mathematical graphics, teachers can only buy and draw on blackboard or paper for explanation. There is no specific production process. Sometimes students are not very interested in learning, and the effect of explanation cannot reach the level of twice the result with half the effort, especially when they can only draw planes. Curve graphics, but can not get three-dimensional graphics of several curves, the effect is not obvious

Abstract

The invention relates to a mathematical graph demonstration teaching aid device and an operation method thereof. The device comprises a grid plate. A left arc plate is attached to the left side of thegrid plate. A left fixing plate is fixedly connected with the back of the left arc plate. The left fixing plate and the grid plate are fixed through a combined fixing piece. The front end of the leftarc plate is fixedly connected with a left elastic plate. A right arc plate is attached to the right side of the grid plate. A right fixing plate is fixedly connected with the back of the right arc plate. The right fixing plate and the grid plate are fixed through another combined fixing piece. A right elastic plate is fixedly connected to the front of the right arc plate. An upper arc plate is attached to the top of the grid plate. An upper fixing plate is fixedly connected to the back of the upper arc plate. The upper fixing plate and the grid plate are fixed through a third combined fixingpiece. The front face of the upper arc plate is fixedly connected with an upper elastic plate. A lower arc plate is attached to the bottom of the grid plate. A lower fixing plate is fixedly connectedwith the back of the lower arc plate. The lower fixing plate and the grid plate are fixed through a fourth combined fixing piece. The front end of the lower arc plate is fixedly connected with a lower elastic plate. The device is used for making a mathematical graph curve.

Description

Technical field: [0001] The invention relates to a mathematical graphic demonstration teaching aid device and an operation method. Background technique: [0002] When explaining mathematical graphics, teachers can only buy and draw on blackboard or paper for explanation. There is no specific production process. Sometimes students are not very interested in learning, and the explanation effect cannot reach the level of twice the result with half the effort, especially when they can only draw planes. Curve graphics, but the three-dimensional graphics of several curves cannot be obtained, and the effect is not obvious. Invention content: [0003] The purpose of the present invention is to provide a kind of mathematical graphic demonstration teaching aid device and operation method that can make several curves at the same time, the position of the curves is clear, and the three-dimensional effect is strong. [0004] Above-mentioned purpose realizes by following technical sche...
