Question 1187425
.
Give the coordinates of the foci, vertices, and co-vertices of the ellipse with equation
(x²/169) + (y²/25) = 1. Sketch the graph and include these points.
~~~~~~~~~~~~~~~


<pre>
The center of the ellipse is at the origin..


The major semi-axis is  a = {{{sqrt(169)}}} = 13;  the minor semi-axis is  b = {{{sqrt(25)}}} = 5.


The vetices are these two points  (-13,0)  and  (13,0).


The co-vertices are two points  (0,-5)  and  (0,5).


The eccentricity is  c = {{{sqrt(13^2-5^2)}}} = 12.


The foci are these two points  (-12,0)  and  (12,0).
