Curve Definition

To define and plot the graph:
-Press Ctrl+F (or select Command->Plot New Graph, or double click on the empty
line of Entry Zone);

-
Choose the curve type you need;
- Enter graph definition using format, correspondent to the curve type;
- Press Enter.
The following curve types are supported:

Cartesian— explicit function in Cartesian coordinates;
Polar — explicit function in polar coordinates;
Parametric — parametric function;
Level line— level lines of explicit function of several arguments  in Cartesian coordinates;
Broken line — a polygon, defined by Cartesian coordinates of its vertices;
Direction field— direction field of defined by explicit function of two variables in
Cartesian coordinates.
Mind definition format in the Microhelp line at the bottom of the screen
Tips:
     To plot graph of implicit function, given by equation F(x, y)=0 select Level line and
enter F(x, y)=0 as graph definition.
     Use
logical and comparison functions to define function by different expressions on
different parts of its domain.
    In curve definition you can use variables, pre-defined in Calculation Mode, or fully
define a curve in Graph Mode.
    Combine using keyboard,
Calculus Panel, and Math Panel, to enter curve definition.
     ArtSGraph gives warning messages in case of syntactical or logical mistakes.
