$$\sin{\left(\frac{\pi x}{4} \right)} = -1$$
Solución detallada
Tenemos la ecuación
$$\sin{\left(\frac{\pi x}{4} \right)} = -1$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$\frac{\pi x}{4} = 2 \pi n + \operatorname{asin}{\left(-1 \right)}$$
$$\frac{\pi x}{4} = 2 \pi n - \operatorname{asin}{\left(-1 \right)} + \pi$$
O
$$\frac{\pi x}{4} = 2 \pi n - \frac{\pi}{2}$$
$$\frac{\pi x}{4} = 2 \pi n + \frac{3 \pi}{2}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$\frac{\pi}{4}$$
obtenemos la respuesta:
$$x_{1} = \frac{4 \left(2 \pi n - \frac{\pi}{2}\right)}{\pi}$$
$$x_{2} = \frac{4 \left(2 \pi n + \frac{3 \pi}{2}\right)}{\pi}$$
