A) \[\infty \]
B) \[{{\tan }^{-1}}(3)\]
C) \[{{\tan }^{-1}}\left( \frac{1}{3} \right)\]
D) None of these
Correct Answer: B
Solution :
\[\theta ={{90}^{o}}-{{\tan }^{-1}}\left( \frac{1}{3} \right)\] \[\tan \theta =\cot \left[ {{\tan }^{-1}}\left( \frac{1}{3} \right) \right]=3\] \[\Rightarrow \theta ={{\tan }^{-1}}(3)\].You need to login to perform this action.
