    Any questions that apply to plotting in Maple will appear here.

    A1: You forgot to specify a range on the independent variable.

     > f:=2-x;
     > plot(f);              WRONG
     Plotting error, empty plot
     > plot(f,x=-1..1);      RIGHT

    A2: You might be plotting a quantity that isn't defined. For example, you might have defined Y but then asked Maple to plot y. Maple is case-sensitive, and many strange behaviors are the result of typing a variable name in the wrong case.

    Another way a plotted quantity can be undefined is if you didn't use the assignment operator := to define it.

     > y=sin(x);              WRONG

The New User's Tour presents the fundamental Maple commands that every user should be aware of. The tour covers many areas of Maple, including: The Maple Worksheet Environment, Numerical Calculations, Algebraic Computations, Graphics, Calculus, Differential Equations, Linear Algebra, Finance and Statistics, Programming, and Online Help. The tour is easy to proceed through, and it can take up to two hours if all topics are examined. In order to start The New User's Tour you should go to Help --> New User's Tour .
