An ellipse and a hyperbola have their principal axes along the coordinate axes and have a common foci separated by distance `2sqrt(3)dot` The difference of their focal semi-axes is equal to 4. If the ratio of their eccentricities is 3/7 , find the equation of these curves.

Text Solution

Verified by Experts

The correct Answer is:
`(x^2)/(49)+(y^(2))/(36)=1; x^2/9=y^2/4=1`
