Solución
Solución detallada
Tenemos la ecuación
$$\sin{\left(t \right)} = - \frac{\sqrt{2}}{2}$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$t = 2 \pi n + \operatorname{asin}{\left(- \frac{\sqrt{2}}{2} \right)}$$
$$t = 2 \pi n - \operatorname{asin}{\left(- \frac{\sqrt{2}}{2} \right)} + \pi$$
O
$$t = 2 \pi n - \frac{\pi}{4}$$
$$t = 2 \pi n + \frac{5 \pi}{4}$$
, donde n es cualquier número entero
