Solución
Solución detallada
Tenemos la ecuación
$$\sin{\left(x \right)} + 1 = 0$$
es la ecuación trigonométrica más simple
Obtenemos:
$$\sin{\left(x \right)} = -1$$
Esta ecuación se reorganiza en
$$x = 2 \pi n + \operatorname{asin}{\left(-1 \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(-1 \right)} + \pi$$
O
$$x = 2 \pi n - \frac{\pi}{2}$$
$$x = 2 \pi n + \frac{3 \pi}{2}$$
, donde n es cualquier número entero
$$\sin{\left(x \right)} + 1 = 0$$
es la ecuación trigonométrica más simple
Transportemos 1 al miembro derecho de la ecuación
cambiando el signo de 1
Obtenemos:
$$\sin{\left(x \right)} = -1$$
Esta ecuación se reorganiza en
$$x = 2 \pi n + \operatorname{asin}{\left(-1 \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(-1 \right)} + \pi$$
O
$$x = 2 \pi n - \frac{\pi}{2}$$
$$x = 2 \pi n + \frac{3 \pi}{2}$$
, donde n es cualquier número entero
