A teaching demonstration instrument for advanced mathematics functions

Abstract

The invention discloses an advanced mathematics function teaching demonstrator, which comprises a base, a telescopic support rod and a demonstration board. A telescopic support rod is connected at that top of the base, and the telescopic support rod is detachably connected with the demonstration board; a guide rail is symmetrically arranged on the front surface of the demonstration board, a horizontal coordinate axis is connected with that vertical slide between the guide rails, a horizontal coordinate axis is slidably connected with a vertical coordinate axis inside the horizontal coordinateaxis, the horizontal axis and the vertical axis are perpendicular to each other, and are provided with graduation marks, the front surface of the demo board is provided with a plurality of equally spaced vertical strip-shaped grooves, each elongated groove begins on the upper surface of the demo board and extends downwardly, an elongated first magnet is arranged inside the elongated groove, a slider is slidably connected up and down in the elongated groove, an elastic rope is detachably connected between adjacent sliders through a fixing device, and a second magnet capable of attracting and engaging with the first magnet is arranged on the inner surface of the slider opposite to the elongated groove. The invention has the advantages of reasonable structure and simple operation, can demonstrate various functions, and effectively lightens the teaching burden of teachers.

Description

technical field [0001] The invention relates to a teaching demonstration instrument, in particular to an advanced mathematics function teaching demonstration instrument. Background technique [0002] Advanced mathematics is a relatively difficult course in college courses. Advanced mathematics is abstract and boring, and students often need to spend more time learning it. [0003] In advanced mathematics teaching, a variety of functions are involved. During the explanation process, in order to enable students to better understand the nature of the function, the teacher will combine the function image to explain the law of the function. Therefore, the teacher needs to draw on the blackboard Various functions. However, the drawing of functions is relatively accurate, and drawing inaccurate functions will directly affect the learning effect of students. The teaching time of teachers in the classroom also increases the teaching burden for teachers. Contents of the invention ...
