$\frac{\tan (x)}{1 + \cos (x)}$

Paso 1

Diferencia con la regla del cociente, que establece que $\frac{d}{d x} [\frac{f (x)}{g (x)}]$ es $\frac{g (x) \frac{d}{d x} [f (x)] - f (x) \frac{d}{d x} [g (x)]}{{g (x)}^{2}}$ donde $f (x) = \tan (x)$ y $g (x) = 1 + \cos (x)$ .

$\frac{(1 + \cos (x)) \frac{d}{d x} [\tan (x)] - \tan (x) \frac{d}{d x} [1 + \cos (x)]}{{(1 + \cos (x))}^{2}}$
