It is easy to graph an equation like y=3x^2+2x-7
as shown in the newbie guide. Is there a similarly
easy method for graphing parametric equations
like x= cos(2t), y=sin(t)?
You can plot parametric equations as well. For examples see:
http://webwork.maa.org/doc/cvs/pg_CURRENT/lib/VectorField.html
and
http://webwork.maa.org/doc/cvs/pg_CURRENT/lib/WWPlot.html
Not everything is well documented so looking at the actual code in those files will help has well.
Here is a directory of problems that use the files:
rochesterLibrary/setDiffEQ2DirectionFields/ur de 2 1-
/ur de 2 1.pg
or
http://cvs.webwork.rochester.edu/viewcvs.cgi/database_problems/Rochester/setDiffEQ2DirectionFields/?cvsroot=Arizona+State+University
hope this helps.

Hi Joel,
Another resource is the WeBWorK Documentation Wiki, http://webwork.maa.org/wiki/Main_Page. Graphing parametric equations is one of the topics on the Index of Problem Techniques in the Authors' section, at http://webwork.maa.org/wiki/Category:Problem_Techniques.
