Example: plotting a circle
Plot the circle, x2+ y2 = 9. First rearrange it to read
y= ±
9 – x2 .
To plot both the positive and negative y values, you need to define two equations as follows:
y = 
9 – x2 and y = – 
9 – x2
1.In the Function aplet, specify the functions.
>$3/(7@ Select
Function 67$57_
>6+,)7@√>@9
>@>;75@>;@>@>(17(5@ >@>6+,)7@√>@9 >@>;75@ >;@>@>(17(5@
2.Reset the graph setup to the default settings.
>6+,)7@CLEAR
3.Plot the two functions and hide the menu so that you can see all the circle.
>3/27@0(18_0(18_
4.Reset the numeric setup to the default settings.
>6+,)7@CLEAR
5.Display the functions in numeric form.
>180@
