To edit an expression, use the mouse or the arrow keys to highlight it in the algebra window. Click on the Edit menu and highlight the Expression sub-menu.

Graphing ² or ³ expressions that have been entered in the Algebra window
If there is already a 2-D plot or 3-D plot window open, merely click on that window. If there is only an Algebra window open, change from the Algebra window to the plot window by using your mouse to open the Window menu and take either the New 2-D plot Window or New 3-D plot Window. Alternately, you can click on the xy icon for ² plots or the xyz icon for ³ plots. Then, click on the Plot! menu, or click again on the icon that transferred you from the Algebra window.

Zooming in and out of graphs
The three arrow out can zoom out on the graph vertically, horizontally or both. The arrow in icons can zoom in on the graph vertically, horizontally or both.

Deleting ² and ³ graphs
The xy plot with an X icon can be used to delete the last ² graph drawn. Other deletions can be accessed under the Edit menu and then the Delete Plot menu. ³ graphs are restricted to one graph per window, so to delete the graph, close the window by clicking on X icon that appears in the upper left-hand corner of that window.

Other useful ² options
To change between Euclidean and Polar coordinates, choose the Options menu followed by the Coordinate System menu. Tracing is controlled by the horizontal arrows keys after choosing the Options menu followed by the Trace Mode.

Evaluation of expressions
Click on the equals icon to calculate an exact, closed answer to your problem. Alternately, you can click on the Simplify menu followed by the Basic sub-menu. Click on the approximate icon to calculate a numerical approximation to your problem. Alternately, you can click on the Simplify menu followed by the Approximate sub-menu.

Manipulation of expressions
Click on the SUB icon to substitute for one of the variables in your expression. Alternately, choose the Simplify menu followed by the Substitute for sub-menu. Click on the Magnifying glass icon to solve your expression for one of the variables. Alternately, choose the Solve menu followed by the Algebraically sub-menu.
