Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0037] see Figure 1-6 , the present invention provides a technical solution:

[0038] A mathematical model for function teaching, comprising a base 1, on which a guide rod 2 arranged in an inverted U shape is fixed, on which a connecting sleeve 8 and a prism 34 are formed, and the connecting sleeve 8 is slidably matched with the guide rod 2 , the top of the base 1 is provided with a frame 3, and the frame 3 and the connecting sleeve 8 are fixed by bolts, the fram...

Abstract

The invention discloses a function teaching mathematical model, which comprises a base, an inverted U-shaped guide rod is fixed on the base, a connecting sleeve is sleeved on the guide rod, a prism is formed on the guide rod, a frame is arranged at the top of the base, the frame and the connecting sleeve are fixed through a bolt, and the connecting sleeve and the prism are fixed through a connecting piece. In the application, each endpoint of a function is determined through a function formula, the connecting seat is pushed to the position of each endpoint, after the connecting block and the rotating block are mounted at the first endpoint through the quick release assembly, the connecting block and the rotating block are mounted at the other endpoints, and the light-emitting wire is pulled outwards; in this state, the light-emitting line is a function image, and compared with the design mode that an LED lamp strip is fixed through a magnet in the prior art, the light-emitting line is higher in stability, not prone to falling off, easy to operate, high in interestingness and beneficial to function teaching.

Description

technical field [0001] The invention relates to the technical field of function teaching, in particular to a mathematical model for function teaching and a method for using the same. Background technique [0002] Function is the foundation of modern mathematics and a corresponding relationship in mathematics. The goal of function is to explore the quantitative relationship and change law in specific problems. Function is also the most important and complex concept in mathematics. Function image is a kind of function Form of expression, to learn functions, you must understand the image of the function. In the current mathematics teaching, teachers often have to draw function images on the blackboard, and the teaching is relatively boring. [0003] For the convenience of students, the dialectical relationship between the positive and negative pairs of the linear function y=kx+b (k≠0) image and the proportional function y=kx image of b=0 and the concept of the positive and nega...
