$\sin (a) + \frac{\cos^{2} (a)}{\sin (a)}$

Step 1

Scomponi $\cos (a)$ da $\cos^{2} (a)$ .

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

Step 2

Frazioni separate.

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

Step 3

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

$\sin (a) + \frac{\cos (a)}{1} \cot (a)$

Step 4

Dividi $\cos (a)$ per $1$ .

$\sin (a) + \cos (a) \cot (a)$
