Many relatives currently say that they have just started geometric painting software software, and they will not construct trigonary function images. So how does the geometric painting board construct trigonites? This article introduces the detailed step method of the geometric painting board constructing the triangle function image. Friends who do n’t understand will follow the editor to learn, I hope it will be helpful to you.

1. Open the geometric board and select the "Data" - "New Function" command. Select the "COS" under the "Function" drop -down menu in the function editing dialog box, and select "X" and "+" in turn. Then select "SIN" in the "Function" drop -down menu, click "X", click "OK", and the function expression appears in the drawing area.

2. Select the function expression, select "Draw" - "Drawing Function" command, and we can see the image.

The detailed steps of the geometric painting board construct triangular function image are explained above. I hope friends who need it to learn.
