$\frac{\sin (B) \sin (B)}{\cos (B)} + \cos (B)$

Passaggio 2

Frazioni separate.

$\frac{\sin (B)}{1} \cdot \frac{\sin (B)}{\cos (B)} + \cos (B)$

Passaggio 3

Converti da $\frac{\sin (B)}{\cos (B)}$ a $\tan (B)$ .

$\frac{\sin (B)}{1} \tan (B) + \cos (B)$

Passaggio 4

Dividi $\sin (B)$ per $1$ .

$\sin (B) \tan (B) + \cos (B)$
