Answer:

Step-by-step explanation:

$\sf Formula: \\\\\sin 2 \theta = 2 \sin \theta \cos \theta$

$\text {\sf \Large Solution :}$

$\cos 2 \theta +\dfrac{\sin \theta\cdot \cos \theta }{\sin 2 \theta } = \\\\\ \cos 2 \theta +\dfrac{\sin \theta\cdot \cos \theta}{2\sin \theta\cdot \cos \theta} =\boxed{\cos 2 \theta +\dfrac{1}{2} }$
