MTH 107 Lecture Notes - Lecture 23: Paraboloid, Precalculus, Joule
Document Summary
Provide a generalization to each of the key terms listed in this section*. Parabola formula d (f, p ) = d (p, d) d (f ocus, p oint) = d (p oint, directrix) The point, which is f , of a parabola. The line, which is d, of a parabola. When the line, which is not meaning the directrix, is going through f , which is the focus and is perpendicular to d, which is the directrix. A parabola"s given point of intersection, which is v , is with its axis of symmetry. Vertex"s satisfying equation d (f, v ) = d (v, d) d (f ocus, v ertex) = d (v ertex, directrix) : directrix: x = a, a > 0. The given line segment is joining two points, which can be (a, 2a) and (a, 2a), with 4a being its length.
