    What are the points of intersection of the curve\[4{{x}^{2}}-9{{y}^{2}}=1\] with its conjugate axis?

    A) \[(1/2,0)\] and \[(-1/2,0)\]

    B) \[(0,2)\] and \[(0,-2)\]

    C) \[(0,3)\] and \[(0,-3)\]

    D) No such point exists

    Correct Answer: D

    Solution :

    [d] The given equation of curve is \[4{{x}^{2}}-9{{y}^{2}}=1\] \[\Rightarrow \frac{{{x}^{2}}}{1/4}-\frac{{{y}^{2}}}{1/9}=1\] This is an equation of a hyperbola which does not intersect with conjugate axes. Hence, no point of intersection exists.
