The following Applet is to help see the geometric interpretation in 5.3.2 of the Binghamton University Course Math 108. Ultimately it is meant to help visualize the relationships between the variables p, h , and k. Recall: The Equation of the Parabola is [math] f(x)=\frac{1}{4p}(x−h)^2+k[/math] The Vertex is (h,k) The Focus is (h,p+k) The Directrix is y=-p+k The value of each variable can be change below. - Created by Raymond Fryc (Adjunct Lecture Math 108 - Fall 2014)
