Question:medium

The value of $ \int \frac{\cos 2x - \cos 2\alpha}{\cos x - \cos \alpha} \, dx $ is:

Show Hint

$\cos \alpha$ is a constant here; do not integrate it as $\sin \alpha$.

Updated On: Apr 8, 2026

$2(\sin x + x \cos \alpha) + c$
$2(\sin x - x \cos \alpha) + c$
$2(\cos x + x \sin \alpha) + c$
None of these
