If you multiply the numerator and the denominator by

(1 + \cos x)^{2}

, you get:

\frac{1}{1 + (\frac{- \sin x}{1 + \cos x})^{2}} = \frac{(1 + \cos x)^{2}}{(1 + \cos x)^{2}} \times \frac{1}{1 + (\frac{- \sin x}{1 + \cos x})^{2}} = \frac{(1 + \cos x)^{2}}{(1 + \cos x)^{2} (1 + (\frac{- \sin x}{1 + \cos x})^{2})} = \frac{(1 + \cos x)^{2}}{(1 + \cos x)^{2} + \sin^{2} x}
