The files we are posting are somewhat advanced in their usage of StudyWorks. On mine (the original post), created a grid of points and removed the points that didn't meet the shading requirements. I had a user-specified region in the graph. Nathan (a later post) used some advanced techniques to try his hand at suggesting a "recommended" region to view. I am sure we could explain our respective files further if necessary.
The StudyWorks Challenge is an opportunity for students to show what they can do with StudyWorks. See the challenge posted at www.studyworksonline.com under Just for Fun. The first two challenges are to make interesting 2D and 3D graphs with StudyWorks, and we'll post your entries on the web site. Craig has been using StudyWorks for a few years now, so don't let his entry intimidate you. We'd like to see what other students can do too. Just post your entries in this forum.
