Suppose an ellipse and a hyperbola have the same pair of foci on the `x`-axis with centres at the origin and they intersect at `(2,2)`. If the eccentricity of the ellipse is `(1)/(2)`, then the eccentricity of the hyperbola, is

A hyperbola has its centre at the origin, passes through the point (4, 2) and has transverse axis of length 4 along the x-axis. Then the eccentricity of the hyperbola is

An ellipse and a hyperbola are confocal (have the same focus) and the conjugate axis of the hyperbola is equal to the minor axis of the ellipse. If e_1a n de_2 are the eccentricities of the ellipse and the hyperbola, respectively, then prove that 1/(e_1^2)+1/(e_2^2)=2 .
