MouseMatics: Mouse Operations in Our Graphing Calculator

Our interactive graphing calculator and specialized graphers, utilizing the most sophisticated Cartesian and polar coordinate systems, allow you to use your mouse to perform unique operations, as outlined below.

How to Rotate Axes

To rotate an axis, hold down the Alt key and click on or near the axis. The axis will be selected and its color will change to red. Move the mouse. The selected axis will rotate accordingly, and the graphs will be redrawn to reflect the axis's rotation. Click again with the Alt key pressed, to release the axis.

To restore the coordinate system to its normal state, press the Reset (rotation) button (if hidden, press the ▼ icon first). You can also rotate axes by entering angles in the provided boxes.

How to Change Scales

To change the scale (zoom in one direction), hold down the ctrl key and click on an axis. The point that was clicked will be labelled 1 if clicked on the positive side, or -1 if clicked on the negative side of the axis; it becomes the new unit for that axis.

How to Translate the Coordinate system

You can move the coordinate system in one of the following ways:

• Click on the canvas and drag the mouse; this will translate the origin and the graphs together.
• Double-click on the canvas to move the origin to the location where you clicked; the graphs are updated.
