Solución

Ha introducido [src]
tan(x) + 1 = 0
$$\tan{\left(x \right)} + 1 = 0$$
Solución detallada
Tenemos la ecuación
$$\tan{\left(x \right)} + 1 = 0$$
es la ecuación trigonométrica más simple
Transportemos 1 al miembro derecho de la ecuación

cambiando el signo de 1

Obtenemos:
$$\tan{\left(x \right)} = -1$$
Esta ecuación se reorganiza en
$$x = \pi n + \operatorname{atan}{\left(-1 \right)}$$
O
$$x = \pi n - \frac{\pi}{4}$$
, donde n es cualquier número entero
