$\frac{1}{\csc^{2} (x)}$

Step 1

Rewrite $1$ as $1^{2}$ .

$\frac{1^{2}}{\csc^{2} (x)}$

Step 2

Rewrite $\frac{1^{2}}{\csc^{2} (x)}$ as ${(\frac{1}{\csc (x)})}^{2}$ .

${(\frac{1}{\csc (x)})}^{2}$

Step 3

Rewrite $\csc (x)$ in terms of sines and cosines.

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

Step 4

Multiply by the reciprocal of the fraction to divide by $\frac{1}{\sin (x)}$ .

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

Step 5

Multiply $\sin (x)$ by $1$ .

$\sin^{2} (x)$
