A) \[{{a}^{2}}+{{b}^{2}}\]
B) \[\sqrt{{{a}^{2}}+{{b}^{2}}}\]
C) \[{{({{a}^{2}}+{{b}^{2}})}^{2}}\]
D) None of these
Correct Answer: B
Solution :
The equation of any tangent to the given ellipse is \[\frac{x}{a}\cos \theta +\frac{y}{b}\sin \theta =1\] This line meets the coordinate axes at \[P\left( \frac{a}{\cos \theta },\,\,0 \right)\]and\[Q\left( 0,\,\,\frac{b}{\sin \theta } \right)\]You need to login to perform this action.
