Solución detallada

Sustituimos $u = \log{\left(\log{\left(\tan{\left(x \right)} \right)} \right)}$ .
Derivado $\log{\left(u \right)}$ es $\frac{1}{u}$ .
Luego se aplica una cadena de reglas. Multiplicamos por $\frac{d}{d x} \log{\left(\log{\left(\tan{\left(x \right)} \right)} \right)}$ :
1. Sustituimos $u = \log{\left(\tan{\left(x \right)} \right)}$ .
2. Derivado $\log{\left(u \right)}$ es $\frac{1}{u}$ .
3. Luego se aplica una cadena de reglas. Multiplicamos por $\frac{d}{d x} \log{\left(\tan{\left(x \right)} \right)}$ :
  1. Sustituimos $u = \tan{\left(x \right)}$ .
  2. Derivado $\log{\left(u \right)}$ es $\frac{1}{u}$ .
  3. Luego se aplica una cadena de reglas. Multiplicamos por $\frac{d}{d x} \tan{\left(x \right)}$ :
    1. Reescribimos las funciones para diferenciar:
      
      $\tan{\left(x \right)} = \frac{\sin{\left(x \right)}}{\cos{\left(x \right)}}$
    2. Se aplica la regla de la derivada parcial:
      
      $\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$
      
      $f{\left(x \right)} = \sin{\left(x \right)}$ y $g{\left(x \right)} = \cos{\left(x \right)}$ .
      
      Para calcular $\frac{d}{d x} f{\left(x \right)}$ :
      1. La derivada del seno es igual al coseno:
        
        $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
      Para calcular $\frac{d}{d x} g{\left(x \right)}$ :
      1. La derivada del coseno es igual a menos el seno:
        
        $\frac{d}{d x} \cos{\left(x \right)} = - \sin{\left(x \right)}$
      Ahora aplicamos la regla de la derivada de una divesión:
      
      $\frac{\sin^{2}{\left(x \right)} + \cos^{2}{\left(x \right)}}{\cos^{2}{\left(x \right)}}$
    Como resultado de la secuencia de reglas:
    
    $\frac{\sin^{2}{\left(x \right)} + \cos^{2}{\left(x \right)}}{\cos^{2}{\left(x \right)} \tan{\left(x \right)}}$
  Como resultado de la secuencia de reglas:
  
  $\frac{\sin^{2}{\left(x \right)} + \cos^{2}{\left(x \right)}}{\log{\left(\tan{\left(x \right)} \right)} \cos^{2}{\left(x \right)} \tan{\left(x \right)}}$
Como resultado de la secuencia de reglas:

$\frac{\sin^{2}{\left(x \right)} + \cos^{2}{\left(x \right)}}{\log{\left(\log{\left(\tan{\left(x \right)} \right)} \right)} \log{\left(\tan{\left(x \right)} \right)} \cos^{2}{\left(x \right)} \tan{\left(x \right)}}$
Simplificamos:

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

Respuesta:

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