quadratic graph properties

some of the properties of y = x squared
only considering the integer points

work developed with David Wells

several interesting applications of:
  • straight line graphs (the chord equations are all neat)
  • mid-points
  • tangents (are parallel to a family of chords)
  • perpendicular line equations
