A) \[\frac{{{x}^{2}}}{{{a}^{2}}}-\frac{9{{y}^{2}}}{{{b}^{2}}}=\frac{1}{9}\]
B) \[\frac{{{x}^{2}}}{{{a}^{2}}}+\frac{9{{y}^{2}}}{{{b}^{2}}}=1\]
C) \[\frac{9{{y}^{2}}}{{{a}^{2}}}+\frac{9{{y}^{2}}}{{{b}^{2}}}=1\]
D) None of these
Correct Answer: B
Solution :
Let\[P(a\cos \theta ,\,\,b\sin \theta ),\,\,Q(a\cos \theta ,\,\,-b\sin \theta )\] Given, \[PR:RQ=1:2\]You need to login to perform this action.
