  1. Check the "sliders" box and play around adjust the values to see the changes in the shape of the parabola.
  2. Check the other boxes EXCEPT the "construction" box. As you mess around with the sliders you'll see the various aspects of the parabola change.
  3. Check the "construction" box. As you drag Point P (the red dot), notice how the distances between the vertex, focus and directrix define the curve.
