E^(cos(x)^x)*tan(x)

Solución detallada

Se aplica la regla de la derivada de una multiplicación:

$\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$

$f{\left(x \right)} = e^{\cos^{x}{\left(x \right)}}$ ; calculamos $\frac{d}{d x} f{\left(x \right)}$ :
1. Sustituimos $u = \cos^{x}{\left(x \right)}$ .
2. Derivado $e^{u}$ es.
3. Luego se aplica una cadena de reglas. Multiplicamos por $\frac{d}{d x} \cos^{x}{\left(x \right)}$ :
  1. No logro encontrar los pasos en la búsqueda de esta derivada.
    
    Perola derivada
    
    $x^{x} \left(\log{\left(x \right)} + 1\right)$
  Como resultado de la secuencia de reglas:
  
  $x^{x} \left(\log{\left(x \right)} + 1\right) e^{\cos^{x}{\left(x \right)}}$
$g{\left(x \right)} = \tan{\left(x \right)}$ ; calculamos $\frac{d}{d x} g{\left(x \right)}$ :
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: $x^{x} \left(\log{\left(x \right)} + 1\right) e^{\cos^{x}{\left(x \right)}} \tan{\left(x \right)} + \frac{\left(\sin^{2}{\left(x \right)} + \cos^{2}{\left(x \right)}\right) e^{\cos^{x}{\left(x \right)}}}{\cos^{2}{\left(x \right)}}$
Simplificamos:

$\frac{\left(x^{x} \log{\left(x \right)} \sin{\left(2 x \right)} + x^{x} \sin{\left(2 x \right)} + 2\right) e^{\cos^{x}{\left(x \right)}}}{\cos{\left(2 x \right)} + 1}$

Respuesta:

$\frac{\left(x^{x} \log{\left(x \right)} \sin{\left(2 x \right)} + x^{x} \sin{\left(2 x \right)} + 2\right) e^{\cos^{x}{\left(x \right)}}}{\cos{\left(2 x \right)} + 1}$
