Solución

Ha introducido [src]
cos(pi*x) = 0
$$\cos{\left(\pi x \right)} = 0$$
Solución detallada
Tenemos la ecuación
$$\cos{\left(\pi x \right)} = 0$$
es la ecuación trigonométrica más simple
cambiando el signo de 0

Obtenemos:
$$\cos{\left(\pi x \right)} = 0$$
Esta ecuación se reorganiza en
$$\pi x = \pi n + \operatorname{acos}{\left(0 \right)}$$
$$\pi x = \pi n - \pi + \operatorname{acos}{\left(0 \right)}$$
O
$$\pi x = \pi n + \frac{\pi}{2}$$
$$\pi x = \pi n - \frac{\pi}{2}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$\pi$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n + \frac{\pi}{2}}{\pi}$$
$$x_{2} = \frac{\pi n - \frac{\pi}{2}}{\pi}$$
