Problem 52E

Eccentricity-directrix approach Find an equation of the following curves, assuming the center is at the origin. Sketch a graph labeling the vertices, foci, asymptotes, and directrices. Use a graphing utility to check your work.An ellipse with vertices (0, ±9) and eccentricity

Step-by-Step Solution:

Solution 52EStep 1:We know the equation of ellipse Has foci(h,Directrix y=Step 2:We have given the ellipse with centre (0,0) vertices (0, ±9) and eccentricity Also Foci (So Hence the equation of ellipse is Hence equation of ellipse is
