$$- \sin{\left(x \right)} - \frac{\sqrt{2}}{2} = 0$$
Solución detallada
Tenemos la ecuación
$$- \sin{\left(x \right)} - \frac{\sqrt{2}}{2} = 0$$
es la ecuación trigonométrica más simple
Transportemos -sqrt(2)/2 al miembro derecho de la ecuación

cambiando el signo de -sqrt(2)/2

Obtenemos:
$$- \sin{\left(x \right)} - \frac{\sqrt{2}}{2} + \frac{\sqrt{2}}{2} = \frac{\sqrt{2}}{2}$$
Dividamos ambos miembros de la ecuación en -1

La ecuación se convierte en
$$\sin{\left(x \right)} = - \frac{\sqrt{2}}{2}$$
Esta ecuación se reorganiza en
$$x = 2 \pi n + \operatorname{asin}{\left(- \frac{\sqrt{2}}{2} \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(- \frac{\sqrt{2}}{2} \right)} + \pi$$
O
$$x = 2 \pi n - \frac{\pi}{4}$$
$$x = 2 \pi n + \frac{5 \pi}{4}$$
, donde n es cualquier número entero
