" If hyperbola "x^(2)-y^(2)=a^(2)" and "xy=c^(2)" are of same size,then: "

If e_(1)ande_(2) be the eccentricities of the hyperbola xy=c^(2)andx^(2)-y^(2)=c^(2) respectively then :

From a point P, tangents are drawn to the hyperbola 2xy = a^(2) . If the chord of contact of these tangents touches the rectangular hyperbola x^(2) - y^(2) = a^(2) , prove that the locus of P is the conjugate hyperbola of the second hyperbola.

The angle between the hyperbola xy = c^(2) " and " x^(2) - y^(2) = a^(2) is

The angle between the hyperbola xy = c^(2) " and " x^(2) - y^(2) = a^(2) is

Angle between the hyperbolas xy=c^(2)" and "x^(2)-y^(2)=a^(2) is

If e and e_1 are the eccentricities of the hyperbola xy=c^(2) ,x^(2) -y^(2) =c^(2) "then" e^(2) +e_1^(2) is equal to

If e and e_(1) , are the eccentricities of the hyperbolas xy=c^(2) and x^(2)-y^(2)=c^(2) , then e^(2)+e_(1)^(2) is equal to

If e and e_(1) , are the eccentricities of the hyperbolas xy=c^(2) and x^(2)-y^(2)=c^(2) , then e^(2)+e_(1)^(2) is equal to

If e and e_(1) , are the eccentricities of the hyperbolas xy=c^(2) and x^(2)-y^(2)=c^(2) , then e^(2)+e_(1)^(2) is equal to
