Coordinate Graphing
The Cartesian coordinate system was
formalized by Rene Descartes in the 17th
century to help visualize functions via
plotting function values as ordered pairs.
In this system a grid of evenly spaced
horizontal and vertical lines is drawn, a
center or "origin" is chosen, and horizontal
and vertical scales are chosen.

Looking for the Top Quark Choose small, medium or large grid and play against the computer. Click "I'm Ready to Start" and place your "quarks" on the grid by filling in the coordinates below the grid. When finished click on "I'm Ready to Start"! Type in your coordinate guesses for the computer's quarks and then indicate on your grid where the computer's guesses are. Beat the computer!
