Q81 / 160 · WBJEE 2009 · Mathematics
Angle between $\mathrm{y}^2=\mathrm{x}$ and $\mathrm{x}^2=\mathrm{y}$ at the origin is
- A$2 \tan ^{-1}\left(\frac{3}{4}\right)$
- B$\tan ^{-1}\left(\frac{4}{3}\right)$
- Correct answerC$\frac{\pi}{2}$
- D$\frac{\pi}{4}$
Solution
Hins : Angle between axes (since co-ordinate axes are the tangents for the given curve).


Hence, the correct answer is option: 'C'.
