Writing the equation of an ellipse given the co vertices and a point

The video tutorial explains how to graph an ellipse by identifying co-vertices and determining the major axis. It covers writing the equation for a vertical major axis and calculating the values of A and B. The tutorial also demonstrates solving for A using a point on the ellipse and finalizing the equation with known values.
