The relationship between function arguments and dependent variables

In a function relationship, a variable that can affect other variables is called an independent variable, and the amount of the variable that changes with the argument is called the dependent variable. Here's how to make the courseware for the relationship between the function arguments and the dependent variables in the geometry artboard .

Discussion on the relationship between function and dependent variables Courseware template sample diagram:

The process of making the courseware is as follows:

1. Drawing handwritten drawings

Select the Marker tool, at which point the mouse is a pen, the left button holds the mouse, and the pen draws a handwritten figure in the artboard.

2. Drawing function Images

Use the move Arrow tool to select the handwriting graphic, click the menu "Data"-"Define drawing function", and get "f (x): Drawing [1]", "F (x): Drawing [1]", click the Menu "Drawing"-"drawing function", at which point the handwriting becomes the function image.

3. Defining fields and ranges for drawing functions

Select the Point tool, in the function image take points A and point B, drag them to the image end point, select the points a, B and X axis, click the menu "Construction"-"vertical line", respectively, point A, point B as vertical x axis perpendicular, with the mouse click the vertical and X axis intersection C and Point D, connect segment CD, that is, the function of the On the segment CD, take the point e, over point e as the x-axis of the vertical intersection function image at F-point, over F point as the y-axis perpendicular, perpendicular to point G; Connect the line segments EF and FG, click on the Menu "Show"-"tracking point", then drag the e-point, can be dynamic observer to define the field and range of the corresponding relationship.

4. Beautify the interface

Select the points and lines you want to hide, click the Menu "Show"-"Hide objects" to keep the interface clean.
