WebFind the Parabola with Focus (1,2) and Directrix y=-2 (1,2) y=-2 Step 1 Since the directrix is vertical , use the equation of a parabola that opens up or down. WebGiven the radii of an ellipse, we can use the equation f 2 = p 2 − q 2 f^2=p^2-q^2 f 2 = p 2 − q 2 f, squared, equals, p, squared, minus, q, squared to find its focal length. Then, the foci will lie on the major axis, f f f f units away from the center (in each direction). Let's find, for example, the foci of this ellipse:
