Geometry Sketchpad is a powerful mathematical drawing software, in which drawing a quadratic parabola is a common operation. However, drawing a cubic parabola requires some skills. PHP editor Xiaoxin will introduce in detail the method of drawing a cubic parabola in this article, allowing you to easily master this practical skill.

Establish a coordinate system. In order to facilitate the viewing of function images here, we do not use the system's own coordinate system. Click [Custom Tools] on the left sidebar, select [Classic Coordinate System] - [Flying Fox | Cartesian Coordinate System] in the pop-up tool menu, and click on the drawing board Click twice and click [Initial Coordinates] to establish the coordinate system as shown in the figure.

Create new parameter a. Click the [Data] menu in the upper menu bar, select the [New Parameter] command in the pop-up drop-down menu, and in the pop-up dialog box, the parameter name is a and the value is 1. Click OK to create a new parameter a.

Draw a cubic parabola. Click the [Draw] menu in the upper menu bar, select the [Draw New Function] command in the pop-up drop-down menu, click [Parameter a,] [*], [x], [^], [3] in the pop-up dialog box, and click OK .

After following the above steps, the image of the cubic parabola will be automatically drawn in the coordinate system.
