Solución detallada
  1. Sustituimos .

  2. Según el principio, aplicamos: tenemos

  3. Luego se aplica una cadena de reglas. Multiplicamos por :

    1. Se aplica la regla de la derivada parcial:

      y .

      Para calcular :

      1. La derivada del seno es igual al coseno:

      Para calcular :

      1. diferenciamos miembro por miembro:

        1. La derivada de una constante es igual a cero.

        2. La derivada del coseno es igual a menos el seno:

        Como resultado de:

      Ahora aplicamos la regla de la derivada de una divesión:

    Como resultado de la secuencia de reglas:

  4. Simplificamos:
