$\frac{2 \sin (A) \cos (A) - \cos (A)}{1 - \sin (A) + \sin^{2} (A) \cos^{2} (A)}$

Etapa 1

Fatore $\cos (A)$ de $2 \sin (A) \cos (A)$ .

$\frac{\cos (A) (2 \sin (A)) - \cos (A)}{1 - \sin (A) + \sin^{2} (A) \cos^{2} (A)}$

Etapa 2

Fatore $\cos (A)$ de $- \cos (A)$ .

$\frac{\cos (A) (2 \sin (A)) + \cos (A) \cdot - 1}{1 - \sin (A) + \sin^{2} (A) \cos^{2} (A)}$

Etapa 3

Fatore $\cos (A)$ de $\cos (A) (2 \sin (A)) + \cos (A) \cdot - 1$ .

$\frac{\cos (A) (2 \sin (A) - 1)}{1 - \sin (A) + \sin^{2} (A) \cos^{2} (A)}$
