Depending on which graphing mode is set, the TI

-86 offers up to seven distinct graph styles.

You can assign these styles to specific functions to visually differentiate each from the others.

For example, you can show 

as a connected line (

 in the equation editor) and 

 as a

dotted line (

), and shade the area above 

 (

).

Also, you can manipulate the styles to illustrate actual phenomena graphically, such as a ball
flying through the air (using  Á) or the circular movement of a chair on a Ferris wheel (using  À).
