Solución

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

Obtenemos:
$$\cos{\left(a \right)} + \cos{\left(a \right)} = 0$$
Dividamos ambos miembros de la ecuación en 2

La ecuación se convierte en
$$\cos{\left(a \right)} = 0$$
Esta ecuación se reorganiza en
$$a = \pi n + \operatorname{acos}{\left(0 \right)}$$
$$a = \pi n - \pi + \operatorname{acos}{\left(0 \right)}$$
O
$$a = \pi n + \frac{\pi}{2}$$
$$a = \pi n - \frac{\pi}{2}$$
, donde n es cualquier número entero
