Solución

Ha introducido [src]
sin(x) - 2*cos(x) = 0
$$\sin{\left(x \right)} - 2 \cos{\left(x \right)} = 0$$
Solución detallada
Tenemos la ecuación
$$\sin{\left(x \right)} - 2 \cos{\left(x \right)} = 0$$
cambiamos:
$$\frac{\sin{\left(x \right)}}{\cos{\left(x \right)}} = 2$$
o
$$\tan{\left(x \right)} = 2$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$x = \pi n + \operatorname{atan}{\left(-2 \right)}$$
O
$$x = \pi n - \operatorname{atan}{\left(2 \right)}$$
, donde n es cualquier número entero
