The geometry artboard attaches the text to the point -and-order steps For example, to attach text to a point, the specific steps are as follows: Step one opens the geometry artboard, draws point A in the blank area, and uses the Text tool to enter text: Follow point a motion, as shown in the following figure. Geometry artboard Step two select point A a

The previous section has implemented the drawing in the artboard, delete, restore into the empty function, as well as the eraser, set the brush size and brush color is not implemented, this section will be implemented one by one.Look first:In, the first shows the ability to set the color of the brush, the second shows the color of the set brush size, and the third shows the function of the eraser, carefully found, this section will set the icon color

Geometric artboards mainly take points, lines, circles as the basic elements, through the transformation of these basic elements, construction, measurement, calculation, animation, tracking track, etc., the construction of other more complex graphics. is a powerful tool in the teaching of mathematics and physics. For a beginner of geometry, it is necessary to understand the production process of geometry drawing board courseware to learn how to use geometrical drawing board to make courseware as

formula and its image changeIn this paper, we introduce the analytic method of the dynamic geometry artboard using the parameters, and use this method to see the relationship between function analytic style and image. The common geometric artboard function images can be implemented using function functions, such as parametric equations of geometric artboards, and the specific tutorials can refer to how the

Step one open the geometry artboard, select the "line tool", in the artboard blank area to draw a horizontal line L, to represent the ground, as shown in the following figure. To draw a horizontal line with a line tool in a geometry artboard L example Step two Select the "Custom Tool" on the left toolbox, click on the mouse, and select "Physical Tool"-"w

A detailed picture and text tutorial on the Lylo triangle of the geometric artboard Lylo triangles, also known as "Le Laur triangles" or "arc triangles", have different names in different cases. It is in addition to the circle, the simplest easy to understand the Le Laur polygon, but also a fixed-width curve. So how can we draw such a triangle? In fact, drawing on the blackboard on the time, you can draw on the use of geometric sketchpad such as prof

In the geometry artboard, the function editor can not only use the basic functions of the system to edit functions, but also perform complex function calculations and draw the image of complex functions. The following is a description of the image of a composite function of a geometric artboard .For example, a known function f (x) =x3-2x-1, drawing an image of two functions f (x) and F (x2).　　The steps are

In the teaching of two functions, using the geometry artboard translation command to create two function images, visually demonstrate the translation of the parabolic line, so that students understand how the parabolic line changes.　　　　The specific production ideas and methods are as follows:The k in the analytic y=ax2+k is used as the parameter, and the change of the parabolic line is realized by the change of the control parameters. Below the parabo

It's possible to draw with parameters.1, first new two parameters a=6 and b=32. Click "Data" → "new Function", f (x) =a*cos (x), g (x) =b*sin (x).3, select the new two functions in 2, click on the "drawing" → "Draw parametric curve", in the popup dialog box, the "Show Arrows and Endpoints" before the check out, the definition field to-π≤t≤π (in the geometry artboard directly enter the letter p, he will automatically become π) Click OK. The ellipse wil

This paper is the official HTML5 training course for Brother Lian it educational institution, the main introduction: HTML5 Mobile Development Road (10)--online artboardIn this article we use HTML5 to implement an online artboard, played you draw my guess friend today can also do a simple you draw I guess the game, the effect as shown:The process is straightforward on the code:[HTML]View PlainCopyprint?

Geometry drawing is Euclidean geometry "ruler of the drawing" of a modern extension, the geometry of the drawing board can be arbitrarily drawn geometry, the geometry of the toolbox is the most used tools to make courseware, the following for you to each of the geometry of the toolbox tools to use the tool. The Geometry artboard Toolbox is located on the left side of the interface, from top to bottom: Select or Drag Object tool, Draw Point tool, Draw
