Equation Of A Parabola

Check us out at http://www.tutorvista.com//videos A parabola is the set of points that are equally distant from the focus point and the directrix. This Tab Tutor program will help you learn about the equation of a parabola and how to use it to derive the focus, vertex, and orientation. A useful glossary also introduces you to other features like the latus rectum and the axis of symmetry. A Prabola is a set of points that are equally distant from the focus point (F) and the directrix , a fixed line. A parabola's standard equation depends on how its axis of symmetry is oriented. A vertical axis has its focus at (h,k+p) and the equation (x-h)^2=4p(y-x), While a horizontal axis has its focus at (h+p,k) and the equation (y-k)^2=4p(x-h). The vertex at (h,k) is half way between the focus and the directrix, at the distance 'p' from both
