1.	If PQ is a double ordinate of the hyperbola x2a2−y2b2=1 such that OPQ is an equilateral triangle, O being the centre of the hyperbola, then (where e is the eccentricity of the hyperbola)
Answer» If $P Q$ is a double ordinate of the hyperbola $\frac{x^{2}}{a^{2}} - \frac{y^{2}}{b^{2}} = 1$ such that $O P Q$ is an equilateral triangle, $O$ being the centre of the hyperbola, then (where $e$ is the eccentricity of the hyperbola)
