With the progress of science and technology, multimedia teaching has appeared in many places of modern teaching, which requires the assistance of some teaching software, and the geometry sketchpad is one of them. The software can not only draw various geometric figures, but also construct function images. In the previous tutorial, we learned how to draw elementary functions such as linear function, quadratic function and logarithmic function with it. Then a friend asked: how to draw the images of two functions in the geometric sketchpad at the same time? Let's learn the specific production skills together.

Case 1: Making images of two functions in the same coordinate system.

Geometric sketchpad can only define one coordinate system by default, so it is easy to make images of two functions in the same coordinate system. The specific steps are as follows:

Step 1: Open the Geometry Sketchpad, click the "Drawing" menu in the menu bar above, select the "Drawing New Function" command from the drop-down options, enter the analytical formula shown in the following figure in the pop-up dialog box, and click OK to draw the function image.

The second step is to follow the above steps, and then input a resolution function to draw a second function diagram. For example, enter the analytical formula f(x)=2x+ 1, and click OK to draw the function image. Two functional images are displayed in the same coordinate system, as shown in the following figure.

Enter the quadratic resolution function and draw an example.

Case 2: Make images of two functions in different coordinate systems.

If you need to draw an image in a different coordinate system, you can use the coordinate system in the custom tool. This coordinate system can be defined many times in the sketchpad, and you can draw a function image in each defined coordinate system. The specific steps are as follows:

Step 1: Establish the first coordinate system and draw the function image. Open the Geometry Sketchpad, click the left sidebar custom tool button, select "Classic Coordinate System"-Flying Fox | Cartesian Coordinate System in the pop-up dialog box, and then click Create Cartesian Coordinate System in the workspace.

Step 2 Click the "Drawing" menu in the menu bar above, select the "Drawing New Function" command from its drop-down options, enter the resolution function in the pop-up dialog box, and click OK to draw a function image, as shown in the following figure.

Establish the first coordinate system and draw an example.

Step 3: Establish the second coordinate system and make the function image. Click the left sidebar custom tool button, select "Mini Coordinate System"-Shiyan | Plane Cartesian Coordinate System in the pop-up dialog box, and then click in the workspace to create Cartesian coordinate system. Then select the coordinate origin and execute the command of "Drawing"-"Defining Coordinate System", and the current coordinate system can be used as the main coordinate system. Then click the "Draw" menu in the menu bar above, select the "Draw New Function" command from its drop-down options, enter the resolution function in the pop-up dialog box, and click OK to draw a function image, as shown in the following figure.

Establish a second coordinate system and draw an example.

The above is the method of making two function images in the geometric sketchpad at the same time, which is divided into the same coordinate system and no longer the same coordinate system. The second situation is relatively complicated. To define who is the current coordinate system, in fact, according to the above method, not only two function images can be drawn, but also more than three can be realized.
