A) \[\left( 1-\frac{1}{{{n}^{2}}} \right)\]
B) \[\frac{1}{1-{{n}^{2}}}\]
C) \[\sqrt{\left( 1-\frac{1}{{{n}^{2}}} \right)}\]
D) \[\sqrt{1-\frac{1}{{{n}^{2}}}}\]
Correct Answer: A
Solution :
\[\,\mu =\tan \theta \,\left( 1-\frac{1}{{{n}^{2}}} \right)=1-\frac{1}{{{n}^{2}}}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,[As\,\,\theta =45{}^\circ ]\]You need to login to perform this action.
