A) \[\left[ \frac{1}{\sqrt{2}},\sqrt{2} \right]\]
B) \[\left( \sqrt{2},\infty \right)\]
C) \[\left( 0,\frac{1}{2} \right)\]
D) \[\left[ \frac{1}{2},\frac{1}{\sqrt{2}} \right]\]
Correct Answer: B
Solution :
We have \[2{{c}^{2}}-{{b}^{2}}>{{b}^{2}}+{{c}^{2}}\] \[\Rightarrow \,{{c}^{2}}>2{{b}^{2}}\] \[\Rightarrow \,\,\,\left| \frac{c}{b} \right|>\sqrt{2}\]You need to login to perform this action.
