This applet allows you to experiment with the equation of a parabola.[br][br]Use the mouse to move the focus.[br][br]Use the slider or the input box to set the right-hand side of the equation of the directrix.

Problems.[br][br]1. Find the equation of the parabola whose focus is F = (3,2) and whose directrix is x = -2. Check your calculations in the applet window.[br][br]2. Find the equation of the parabola whose focus is F = (3,-2) and whose directrix is y = 1. Check your calculations in the applet window.
