Answer & Solution

Correct Answer

(A) \(\tan ^{-1} \frac{5}{\sqrt{3}}\)

Step-by-step Solution

Detailed explanation

Given curves are On solving Eqs. (i) and (ii), we get \[ \therefore \quad x= \pm \sqrt{3}, y=1 \] Thus, their points of intersection are \((\sqrt{3}, 1)\) and \((-\sqrt{3}, 1)\). Now, from Eq. (i), \(\frac{d y}{d x}=\frac{2 x}{3}\) and from Eq. (ii),…
