Maple provides plotting commands for a variety of different types of objects in two and three dimensions. For a more comprehensive list of commands, a detailed discussion of their syntax and features, and numerous examples, see the on-line Help Browser in Maple.
Each plotting command requires an expression (or expressions) in a variable and the domain for the variable.. Maple then samples a meaningful set (or grid) of points in the domain and displays the results for you according to the routine of the particular plotting command. These expressions can be symbolic formulas in the plotting variables, function definitions that you have made, or sets of data. For example, if you have made the function definition in Maple
f:=x -> 3*x^2 - sin(x);you could use
f(x) in any Maple routine in which you wanted
to evaluate, manipulate, or plot the function 
. We can also define functions of more than one independent
variable. For example,
f:= (x,y) -> x^2 - 3*y^2;defines the function
. Below we will use symbols
f(x), f(x,y), g(x), etc. for expressions in Maple rather than
particular expressions in the variables. Remember, Maple will not
evaluate any expression involving these symbols if they have not been
defined prior to their use.
Each plotting command requires the domain of the independent
variables. We will express these in the form x = a..b where
a and b can either be explicit numerical values or
constants whose values have been assigned prior to their use.
Note: All the plotting commands except for plot
and plot3d are contained in the external package plots,
which must be loaded using
with(plots);before you can use its plotting commands.
