With the given focus and directrix, determine the vertex of the parabola. Substitute the obtained vertex in the vector form of parabola. Again, with the values of {eq}a {/eq}, the quadratic equation is obtained. How does one find the focus and directrix? In vertex form if, {eq}(x -...
A parabola is a locus of points equidistant from both 1) a single point, called the focus of the parabola, and 2) a line, called the directrix of the parabola. What is the Focus and Directrix? The red point in the pictures below is the focus of the parabola and the red line is ...
