Consider the system of hyperbola `xy = k, k in R`. Let `e_1` be the eccentricity when k = 4 and `e_2` be the eccentricity when k = 9, then `e_1-e_2`

Consider the set the of hyperbola xy = k, k in R . Let e_(1) be the eccentricity when k = 4 and e_(2) be the eccentricity when k = 9 then e_(1) - e_(2) =

If e1 and e2 are the eccentricities of a hyperbola and its conjugates then ,

If e_(1) and e_(2) are the eccentricities of a hyperbola and its conjugate then

If e_1 and e_2 be the eccentricities of two conjugate hyperbola, then 1/e_1^2+1/e_2^2 is :

If e and e' be the eccentricities of a hyperbola and its conjugate , then 1/e^2+1/(e'^2) equals :

If e_1 is eccentricity of the ellipse x^2/16+y^2/7=1 and e_2 is eccentricity of the hyperbola x^2/9-y^2/7=1 , then e_1+e_2 is equal to:
