Solución

Ha introducido [src]
sin(sin(sin(x)))
sin(sin(sin(x)))\sin{\left(\sin{\left(\sin{\left(x \right)} \right)} \right)}
sin(sin(sin(x)))
Solución detallada
  1. Sustituimos u=sin(sin(x))u = \sin{\left(\sin{\left(x \right)} \right)}.

  2. La derivada del seno es igual al coseno:

    ddusin(u)=cos(u)\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}

  3. Luego se aplica una cadena de reglas. Multiplicamos por ddxsin(sin(x))\frac{d}{d x} \sin{\left(\sin{\left(x \right)} \right)}:

    1. Sustituimos u=sin(x)u = \sin{\left(x \right)}.

    2. La derivada del seno es igual al coseno:

      ddusin(u)=cos(u)\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}

    3. Luego se aplica una cadena de reglas. Multiplicamos por ddxsin(x)\frac{d}{d x} \sin{\left(x \right)}:

      1. La derivada del seno es igual al coseno:

        ddxsin(x)=cos(x)\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}

      Como resultado de la secuencia de reglas:

      cos(x)cos(sin(x))\cos{\left(x \right)} \cos{\left(\sin{\left(x \right)} \right)}

    Como resultado de la secuencia de reglas:

    cos(x)cos(sin(x))cos(sin(sin(x)))\cos{\left(x \right)} \cos{\left(\sin{\left(x \right)} \right)} \cos{\left(\sin{\left(\sin{\left(x \right)} \right)} \right)}


Respuesta:

cos(x)cos(sin(x))cos(sin(sin(x)))\cos{\left(x \right)} \cos{\left(\sin{\left(x \right)} \right)} \cos{\left(\sin{\left(\sin{\left(x \right)} \right)} \right)}
