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