$\frac{(\sin (v)) \cdot (\cos (v))}{(\cos^{2} (v)) - (\sin^{2} (v))}$

Step 1

Since both terms are perfect squares, factor using the difference of squares formula, $a^{2} - b^{2} = (a + b) (a - b)$ where $a = \cos (v)$ and $b = \sin (v)$ .

$\frac{\sin (v) \cos (v)}{(\cos (v) + \sin (v)) (\cos (v) - \sin (v))}$
