How to write the equation of a parabola given focus and directrix

The video tutorial explains how to plot conic sections, focusing on the concepts of focus, directrix, and vertex. It demonstrates how to determine the vertex by finding the equidistant point between the focus and directrix. The tutorial also covers the orientation of parabolas and how to formulate their equations. The importance of plotting information to understand conic sections is emphasized throughout.
