1.If x2cos2α−y2sin2α=1\frac{x^2}{\cos^2 \alpha} - \frac{y^2}{\sin^2 \alpha} = 1cos2αx2−sin2αy2=1 represents family of hyperbolas where α\alphaα varies then -a.distance between the foci is constantb.distance between the two directrices is constantc.distance between the vertices is constantd.distances between focus and the corresponding directrix is constantLogin to continueOnly logged in users canattempt or see the solution.
