A) \[\frac{a}{b}\]
B) \[\sqrt{ab}\]
C) \[ab\]
D) \[2ab\]
Correct Answer: D
Solution :
The parametric coordinates of a point that lies on an ellipse \[\frac{{{x}^{2}}}{{{a}^{2}}}\,+\frac{{{y}^{2}}}{{{b}^{2}}}\,=1\] are \[(a\cos \theta ,\,b\sin \theta )\]. Let the coordinates of the vertices of rectangle ABCD beYou need to login to perform this action.
