Solución

Ha introducido [src]
sin(3*x + 2) = 0
$$\sin{\left(3 x + 2 \right)} = 0$$
Solución detallada
Tenemos la ecuación
$$\sin{\left(3 x + 2 \right)} = 0$$
es la ecuación trigonométrica más simple
cambiando el signo de 0

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