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

1/(sin(2*x)^2)

Detail solution

Let $u = \sin^{2}{\left(2 x \right)}$ .
Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \sin^{2}{\left(2 x \right)}$ :
1. Let $u = \sin{\left(2 x \right)}$ .
2. Apply the power rule: $u^{2}$ goes to $2 u$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \sin{\left(2 x \right)}$ :
  1. Let $u = 2 x$ .
  2. The derivative of sine is cosine:
    
    $\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} 2 x$ :
    1. The derivative of a constant times a function is the constant times the derivative of the function.
      1. Apply the power rule: $x$ goes to $1$
      So, the result is: $2$
    The result of the chain rule is:
    
    $2 \cos{\left(2 x \right)}$
  The result of the chain rule is:
  
  $4 \sin{\left(2 x \right)} \cos{\left(2 x \right)}$
The result of the chain rule is:

$- \frac{4 \cos{\left(2 x \right)}}{\sin^{3}{\left(2 x \right)}}$

The answer is:

$- \frac{4 \cos{\left(2 x \right)}}{\sin^{3}{\left(2 x \right)}}$
