An equation of an ellipse is given. 1 16 164 (a) Find the vertices, foci, and eccentricity of the ellipse. vertex ( X , y ) = (smaller y-value) vertex ( X, y )= (larger y-value) focus (X, Y) = (smaller y-value) focus (x, Y)H (larger y-value) eccentricity (b) Determine the length of the major axis. Determine the length of the minor axis
