  • Plot many equations on one graph!
  • Use the pen to determine a particular (x,y) coordinate
  • Define your own  graph (x,y) limits
  • Zoom and scroll the display
  • Perform 'normal' calculations using the in-built paper tape and memory
  • Perform trigonometric calculations including hyperbolics, inverses, degrees and radians
