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