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

Obtenemos:
$$\sin{\left(x + \frac{3 \pi}{4} \right)} = 0$$
Esta ecuación se reorganiza en
$$x + \frac{\pi}{4} = \pi n + \operatorname{acos}{\left(0 \right)}$$
$$x + \frac{\pi}{4} = \pi n - \pi + \operatorname{acos}{\left(0 \right)}$$
O
$$x + \frac{\pi}{4} = \pi n + \frac{\pi}{2}$$
$$x + \frac{\pi}{4} = \pi n - \frac{\pi}{2}$$
, donde n es cualquier número entero
Transportemos
$$\frac{\pi}{4}$$
al miembro derecho de la ecuación
con el signo opuesto, en total:
$$x = \pi n + \frac{\pi}{4}$$
$$x = \pi n - \frac{3 \pi}{4}$$
