How to use the geometric sketchpad to draw the image of the function y=x^3? This tutorial will show you how to use Geometric Sketchpad, a powerful geometric drawing software, to plot the graph of this function. Here's what you'll cover in this tutorial: Creating a new Geometry Sketchpad document. Draw a coordinate system. Define functions. Plot the graph of the function. Read on to learn the detailed steps for graphing the function y=x^3 and master the power of the Geometry Sketchpad.
1. Execute the [Draw]-[Define Coordinate System] command to create a new coordinate system and set the label of the origin coordinate to O.
2. Select the x-axis of the coordinate system, execute the [Construct]-[Point on Axis] command to construct point B.
3. Select point B and execute the [Measure]-[Abscissa] command to measure the abscissa xB of point B.
4. Select the abscissa xB of point B, execute the [Measure]-[Calculate] command, and calculate the value of xB3 in the pop-up new calculation dialog box.
5. Select the abscissa coordinate xB and the measurement value xB3 of point B in turn, execute the [Draw]-[Draw Point (x, y)] command to draw point C (xB, xB3).
6. Select point C and point B in sequence (the order must not be wrong), execute the [Construct]-[Trajectory] command, and you can draw the image of the function y=x3. Execute the [Draw]-[Hide Grid] command to hide the grid in the coordinate system.
7. Execute the [File]-[Save] command.
