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

Passaggio 1

Scomponi $\sin (x)$ da $\sin^{2} (x)$ .

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

Passaggio 2

Frazioni separate.

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

Passaggio 3

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

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

Passaggio 4

Converti da $\frac{1}{\sin (x)}$ a $\csc (x)$ .

$\csc (x) \cot (x) + \frac{\cos (x)}{\sin (x)}$

Passaggio 5

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

$\csc (x) \cot (x) + \cot (x)$
