Solución
Solución detallada
Tenemos la ecuación
$$\cos{\left(t \right)} = \frac{\sqrt{2}}{2}$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$t = \pi n + \operatorname{acos}{\left(\frac{\sqrt{2}}{2} \right)}$$
$$t = \pi n - \pi + \operatorname{acos}{\left(\frac{\sqrt{2}}{2} \right)}$$
O
$$t = \pi n + \frac{\pi}{4}$$
$$t = \pi n - \frac{3 \pi}{4}$$
, donde n es cualquier número entero
