$$\frac{\sin{\left(x^{3} \right)}}{3} = 0$$
Solución detallada
Tenemos la ecuación
$$\frac{\sin{\left(x^{3} \right)}}{3} = 0$$
cambiamos
$$\frac{\sin{\left(x^{3} \right)}}{3} - 1 = 0$$
$$\frac{\sin{\left(x^{3} \right)}}{3} - 1 = 0$$
Sustituimos
$$w = \sin{\left(x^{3} \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$\frac{w}{3} = 1$$
Dividamos ambos miembros de la ecuación en 1/3
w = 1 / (1/3)

Obtenemos la respuesta: w = 3
hacemos cambio inverso
$$\sin{\left(x^{3} \right)} = w$$
sustituimos w:
