Solución
Solución detallada
Tenemos la ecuación
$$\sin{\left(t \right)} = - \frac{1}{2}$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$t = 2 \pi n + \operatorname{asin}{\left(- \frac{1}{2} \right)}$$
$$t = 2 \pi n - \operatorname{asin}{\left(- \frac{1}{2} \right)} + \pi$$
O
$$t = 2 \pi n - \frac{\pi}{6}$$
$$t = 2 \pi n + \frac{7 \pi}{6}$$
, donde n es cualquier número entero
