$$\sin{\left(\frac{x}{2} \right)} + 1 = 0$$
Solución detallada
Tenemos la ecuación
$$\sin{\left(\frac{x}{2} \right)} + 1 = 0$$
es la ecuación trigonométrica más simple
Transportemos 1 al miembro derecho de la ecuación

cambiando el signo de 1

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