The eccentricity of an ellipse is defined as e = c/a. For an ellipse, 0<c<a, so 0<e<1. When e is close to 0, an ellipse appears to be nearly circular. When e is close to 1, an ellipse is very flat. Find an equation of an ellipse with vertices (0, -5) and (0,5) and e= 2/5 The equation of an ellipse which satisfies the given conditions is (Type your answer in standard form.)
