Vedclass · Answer

(C) Let $I = \int \frac{dx}{\cos x + \sqrt{3} \sin x}$.Multiply and divide by $2$:$I = \int \frac{dx}{2 \left( \frac{1}{2} \cos x + \frac{\sqrt{3}}{2} \sin x ight)}$.Using $\sin \frac{\pi}{6} = \frac{1}{2}$ and $\cos \frac{\pi}{6} = \frac{\sqrt{3}}{2}$:$I = \frac{1}{2} \int \frac{dx}{\sin \frac{\pi}{6} \cos x + \cos \frac{\pi}{6} \sin x}$.Using the formula $\sin(A+B) = \sin A \cos B + \cos A \sin B$:$I = \frac{1}{2} \int \frac{dx}{\sin(x + \frac{\pi}{6})} = \frac{1}{2} \int \csc(x + \frac{\pi}{6}) dx$.Using the standard integral $\int \csc 	heta d	heta = \log |	an \frac{	heta}{2}| + C$:$I = \frac{1}{2} \log |	an(\frac{x}{2} + \frac{\pi}{12})| + C$.
