Enter and graph functions and parametric expressions using this syntax. To graph two or more functions on the same coordinate plane you may have to display the scrollable multi-graph pane by clicking » on the top left of the graph canvas. The multi-graph pane consists of expression panels, either of which can be inserted or deleted as desired by pressing or ✖ on each panel, respectively. Selecting or deselecting the checkbox for any expression displays or hides the corresponding graph.
You can set the accuracy of the graphs by selecting an option from Graph Accuracy drop-down list. In general, the higher the accuracy, the longer it takes to graph expressions.
To evaluate a function or a parametric expression type in a number or a numeric (constant) expression in the box provided; the function or parametric values are displayed automatically with the number of decimal places which can be specified by using the slider provided.
When you select Polar from the top right of the graphing canvas, the polar coordinate system will be displayed and the graphs are drawn on it. By pressing Animate you can see how polar graphs or Parametric graphs are constructed. You can Pause and Run the animation by using the panel which now appears on the bottom of the Graphing Calculator. You can also change the speed of graphing animation by using the slider provided.
You can set the following options by pressing the (gear) button on the top left corner of the graph canvas; a scrollable transparent or opaque pane is displayed.
Note: Since the values of trigonometric functions depend on the angle mode you select, the graphs of expressions containing trigonometric functions will, as expected, differ as you change from RAD mode (default) to other modes.

In addition to inputting data — by first pressing the gear button — you can use your mouse to perform some functionality unique to this interactive graphing calculator as outlined below.
Note: If Graph As You Interact is selected, the graphs are automatically updated when performing the above, and in general, any interaction with the graphing calculator, i.e., typing, mouse operations and clicking a button. Otherwise, you have to press Graph Selected Expressions to reflect the changes you have made.
