$$\sin{\left(2 z + \frac{\pi}{4} \right)} = 0$$
Solución detallada
Tenemos la ecuación
$$\sin{\left(2 z + \frac{\pi}{4} \right)} = 0$$
es la ecuación trigonométrica más simple
cambiando el signo de 0

Obtenemos:
$$\sin{\left(2 z + \frac{\pi}{4} \right)} = 0$$
Esta ecuación se reorganiza en
$$2 z + \frac{\pi}{4} = 2 \pi n + \operatorname{asin}{\left(0 \right)}$$
$$2 z + \frac{\pi}{4} = 2 \pi n - \operatorname{asin}{\left(0 \right)} + \pi$$
O
$$2 z + \frac{\pi}{4} = 2 \pi n$$
$$2 z + \frac{\pi}{4} = 2 \pi n + \pi$$
, donde n es cualquier número entero
Transportemos
$$\frac{\pi}{4}$$
al miembro derecho de la ecuación
con el signo opuesto, en total:
$$2 z = 2 \pi n - \frac{\pi}{4}$$
$$2 z = 2 \pi n + \frac{3 \pi}{4}$$
Dividamos ambos miembros de la ecuación obtenida en
$$2$$
obtenemos la respuesta:
$$z_{1} = \pi n - \frac{\pi}{8}$$
$$z_{2} = \pi n + \frac{3 \pi}{8}$$
