Embodiment 1

[0039] Such as 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 ...

Embodiment 2

[0045] 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:

[0046] S1. Fix the first corner seat 1 and the fixed side 4, and rotate the hypotenuse part 2;

[0047]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;

[0048] 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.

[0049] In a preferred solution, the main control device 7 controls the li...

Embodiment 3

[0052] 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;

[0053] 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 a trackless trolley and a construction method for transporting reinforcement mesh sheets of the face of a rockfill dam. The bottom of the trolley frame is provided with a plurality of walking tire devices, and the walking tire devices are connected to the trolley frame through a lifting mechanism; The bottom of the vehicle frame is also provided with a plurality of liftable hooks. The construction method includes the following steps: when the walking tire device of the trackless trolley transfers the steel mesh sheet on the post-casting block, the height of the trolley is adjusted to suit the construction site through the cooperation of the lifting mechanism and the liftable hook, and the liftable hook is hung Steel mesh, use the trolley to transport the steel mesh to the set position, after completing the layout of the current row of steel mesh, move the trackless trolley to other rows, and continue the above steps; realize the transfer of the steel mesh through the above steps . Through the set up and down walking tire device, it can adapt to the rapid installation, transfer, and quick installation and construction of steel mesh sheets with various thicknesses of panels in the construction of first pouring blocks and post-casting blocks.

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 ...
