Transform

Detail solution

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

$\frac{2 \log{\left(\sin{\left(x \right)} \right)} \cos{\left(x \right)}}{\log{\left(3 \right)}^{2} \sin{\left(x \right)}}$
Now simplify:

$\frac{2 \log{\left(\sin{\left(x \right)} \right)}}{\log{\left(3 \right)}^{2} \tan{\left(x \right)}}$

The answer is:

$\frac{2 \log{\left(\sin{\left(x \right)} \right)}}{\log{\left(3 \right)}^{2} \tan{\left(x \right)}}$
