Etapa 1

Reescreva $\sec (x)$ em termos de senos e cossenos.

$\frac{1}{\cos (x)} \sin^{2} (x)$

Etapa 2

Combine $\frac{1}{\cos (x)}$ e $\sin^{2} (x)$ .

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

Etapa 3

Fatore $\sin (x)$ de $\sin^{2} (x)$ .

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

Etapa 4

Separe as frações.

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

Etapa 5

Converta de $\frac{\sin (x)}{\cos (x)}$ em $\tan (x)$ .

$\frac{\sin (x)}{1} \tan (x)$

Etapa 6

Divida $\sin (x)$ por $1$ .

$\sin (x) \tan (x)$
