You may enter data in this applet in two ways. In "Function form" y is a function of x. In ‘Parametric form’ both x and y are functions of a parameter t. You can choose functions in either case from the menu given or enter or change them from your keyboard.

The boxes below allow you to enter the plotting ranges . If you activate ‘show point on curve’ by clicking on it, you can wander using the slider or incremental mover to see values of variables and where they are on the curve. Don’t forget to click on ‘plot function’ when you make new entries.
