MCQ
Angle between $x = 2$ and $x - 3y = 6$ is
- A$\infty $
- ✓${\tan ^{ - 1}}(3)$
- C${\tan ^{ - 1}}\left( {\frac{1}{3}} \right)$
- DNone of these
✓
Answer
Correct option: B.
${\tan ^{ - 1}}(3)$
b
(b) $\theta = {90^o} - {\tan ^{ - 1}}\left( {\frac{1}{3}} \right)$
(b) $\theta = {90^o} - {\tan ^{ - 1}}\left( {\frac{1}{3}} \right)$
$\tan \theta = \cot \left[ {{{\tan }^{ - 1}}\left( {\frac{1}{3}} \right)} \right] = 3$
$ \Rightarrow \theta = {\tan ^{ - 1}}(3)$.
