What are the focus and directrix in a parabola with conic sections

The video tutorial covers the concept of parabolas, starting with their standard form and transformations. It introduces a new definition of parabolas using the focus and directrix, explaining how these elements help in graphing and solving parabolas. The tutorial emphasizes the importance of understanding the equidistant property of parabolas from a point (focus) to a line (directrix).
