sin (x)

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

1/(sin(x)^2)

Detail solution

Let $u = \sin^{2}{\left(x \right)}$ .
Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \sin^{2}{\left(x \right)}$ :
1. Let $u = \sin{\left(x \right)}$ .
2. Apply the power rule: $u^{2}$ goes to $2 u$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \sin{\left(x \right)}$ :
  1. The derivative of sine is cosine:
    
    $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
  The result of the chain rule is:
  
  $2 \sin{\left(x \right)} \cos{\left(x \right)}$
The result of the chain rule is:

$- \frac{2 \cos{\left(x \right)}}{\sin^{3}{\left(x \right)}}$

The answer is:

$- \frac{2 \cos{\left(x \right)}}{\sin^{3}{\left(x \right)}}$
