$$\sin{\left(4 x - \frac{\pi}{3} \right)} = 0$$
Solución detallada
Tenemos la ecuación
$$\sin{\left(4 x - \frac{\pi}{3} \right)} = 0$$
es la ecuación trigonométrica más simple
cambiando el signo de 0

Obtenemos:
$$\sin{\left(4 x - \frac{\pi}{3} \right)} = 0$$
Dividamos ambos miembros de la ecuación en -1

La ecuación se convierte en
$$\cos{\left(4 x + \frac{\pi}{6} \right)} = 0$$
Esta ecuación se reorganiza en
$$4 x + \frac{\pi}{6} = \pi n + \operatorname{acos}{\left(0 \right)}$$
$$4 x + \frac{\pi}{6} = \pi n - \pi + \operatorname{acos}{\left(0 \right)}$$
O
$$4 x + \frac{\pi}{6} = \pi n + \frac{\pi}{2}$$
$$4 x + \frac{\pi}{6} = \pi n - \frac{\pi}{2}$$
, donde n es cualquier número entero
Transportemos
$$\frac{\pi}{6}$$
al miembro derecho de la ecuación
con el signo opuesto, en total:
$$4 x = \pi n + \frac{\pi}{3}$$
$$4 x = \pi n - \frac{2 \pi}{3}$$
Dividamos ambos miembros de la ecuación obtenida en
$$4$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n}{4} + \frac{\pi}{12}$$
$$x_{2} = \frac{\pi n}{4} - \frac{\pi}{6}$$
