$$2 \sin{\left(x - \frac{\pi}{4} \right)} - \sqrt{2} = 0$$
Solución detallada
Tenemos la ecuación
$$2 \sin{\left(x - \frac{\pi}{4} \right)} - \sqrt{2} = 0$$
es la ecuación trigonométrica más simple
Transportemos -sqrt(2) al miembro derecho de la ecuación

cambiando el signo de -sqrt(2)

Obtenemos:
$$2 \sin{\left(x - \frac{\pi}{4} \right)} = \sqrt{2}$$
Dividamos ambos miembros de la ecuación en -2

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