- = T" > P 15. Let the focal point F be at the origin, the horizontal line y = -2 be the directrix, and P = (r;0) be equidistant from the focus and the directrix. Using the polar variables r and 0, write an equation that says that the distance from P to the directrix equals the distance from P to F. The configuration of all such P is a familiar curve; make a rough sketch of it. Then rearrange your equation so that it becomes 2 and graph this familiar curve. On which polar ray does 1 – sin 0 no point appear? F + r 2 Y = -2
