Find the ec

Answer :

Given the equation of the ellipse is 5x2 + 4y2 = 1.


We need to find the eccentricity, coordinates of foci and length of latus rectum.



Given equation can be rewritten as .


We know for the ellipse (b2>a2)



Coordinates of foci (0,±be)


Length of latus rectum =


Here and , b2>a2







Length of latus rectum (L) =



The eccentricity is , foci are and length of the latus rectum is .
