Take a another look at ellipses. The seventh segment in a series of 23 in a Precalculus module continues to investigate the graph and equation of an ellipse from the previous lesson. Scholars investigate the fact that the sum of distances from the foci to an ellipse is constant. Learners then develop equations and graph ellipses given the foci.
