    Para calcular ddxg(x)\frac{d}{d x} g{\left(x \right)}:

    1. Sustituimos u=x3+3u = x^{3} + 3.

    2. Según el principio, aplicamos: u3u^{3} tenemos 3u23 u^{2}

    3. Luego se aplica una cadena de reglas. Multiplicamos por ddx(x3+3)\frac{d}{d x} \left(x^{3} + 3\right):

      1. diferenciamos x3+3x^{3} + 3 miembro por miembro:

        1. La derivada de una constante 33 es igual a cero.

        2. Según el principio, aplicamos: x3x^{3} tenemos 3x23 x^{2}

        Como resultado de: 3x23 x^{2}

      Como resultado de la secuencia de reglas:

      9x2(x3+3)29 x^{2} \left(x^{3} + 3\right)^{2}

    Ahora aplicamos la regla de la derivada de una divesión:
