Embodiment 1

[0032] like Figure 1~2 , 6 to 9, an interactive trigonometric function teaching device, which includes a first corner seat 1, a corner sensor is arranged in the first corner seat 1, a corner sensor fixing part 101 is fixedly connected to the fixed side 4, and the corner sensor rotating part 104 is fixedly connected with the hypotenuse part 2, the rotation angle sensor is electrically connected with the main control device 7, the first corner seat 1 is used to transmit the rotation angle of the hypotenuse part 2 to the main control device 7, and the main control device 7 is used for communicating with the display device 8 electrical connection. The rotation angle sensor in this example adopts the Hall non-contact angular displacement sensor. Fix the first corner seat 1 and the fixed part 101, and rotate the hypotenuse part 2 to obtain the angle change between the hypotenuse part 2 and the fixed part 101, so that the parameters and graphs of the corresponding trigonometric fun...

Embodiment 2

[0038] On the basis of Example 1, such as Figure 5 Among them, a method for using the above-mentioned interactive trigonometric function teaching device comprises the following steps:

[0039] S1. Fix the first corner seat 1 and the fixed side 4, and rotate the hypotenuse part 2;

[0040] S2, along with the rotation of the hypotenuse part 2, the main control device 7 transmits the changes of various parameters and / or images of the trigonometric function to the display device 8;

[0041] Through the above steps, the interactive trigonometric function teaching is realized. Especially when the students rotate the hypotenuse 2 by themselves, the display device 8 of the audio-visual education system displays the changes of various parameters, formulas and graphs of trigonometric functions in real time, especially the effect of real-time conversion of function graphs, greatly improving teaching efficiency.

[0042] In a preferred solution, the main control device 7 controls the l...

Embodiment 3

[0045] Another alternative such as image 3 , 4 Among them, an interactive trigonometric function teaching device, it includes a second corner seat 5, a corner sensor is arranged in the second corner seat 5, the fixed part of the corner sensor is fixedly connected with the third fixed seat 504, and the rotating part of the corner sensor is connected with the third fixed seat 504. The stay wire sensor 501 is fixedly connected, the stay wire 502 of the stay wire sensor 501 is fixedly connected with the moving seat 6, and the fixed part of the angle sensor is also fixedly connected with the fixed side 4;

[0046] The rotation angle sensor and cable sensor 501 are electrically connected to the main control device 7 for transmitting the rotation angle and length of the cable 502 to the main control device 7 , and the main control device 7 is used for electrical connection with the display device 8 . With this solution, in addition to reflecting the change of the rotation angle bet...

Abstract

The invention provides an interactive trigonometric function teaching device and method, which includes a first corner seat, a corner sensor is arranged inside the first corner seat, the fixed part of the corner sensor is fixedly connected with the fixed side, and the rotating part of the corner sensor is fixed to the hypotenuse part connection, the rotation angle sensor is electrically connected to the main control device, the first corner seat is used to transmit the angle of the hypotenuse to the main control device, and the main control device is used to electrically connect to the display device. By combining the angle sensor with the main control device, interactive trigonometric function teaching can be realized through the display device or the large-screen display device of the wireless transmission device, that is, students can observe it in real time and intuitively by turning the hypotenuse or the pull wire. The change of each parameter of trigonometric functions, the change trend of parameters, the change of common value, the change of graph and the principle of graph conversion.

Description

technical field [0001] The invention relates to the field of teaching devices, in particular to an interactive trigonometric function teaching device and method. Background technique [0002] The current knowledge inheritance is mostly based on the teaching method of books. Students read books combined with teacher's explanations to learn, which is inefficient, especially for boring mathematics, physics and chemistry knowledge. Low. At present, knowledge is growing at an unprecedented rate, so that human beings need to spend a lot of time on learning and consolidating knowledge. It takes at least 19 years to go from elementary school to doctorate. There are also teaching methods using audio-visual teaching in the prior art, but in actual work, audio-visual teaching is only used to play teaching materials such as ppt, and the interactive ability is not strong. One is that teachers, as non-professionals, lack the ability to write more interactive software; the other is that ...
