cos(x) = \/ 2 *sin(x)
$$\cos{\left(x \right)} = \sqrt{2} \sin{\left(x \right)}$$
Solución detallada
Tenemos la ecuación
$$\cos{\left(x \right)} = \sqrt{2} \sin{\left(x \right)}$$
cambiamos:
$$- \frac{\sqrt{2} \sin{\left(x \right)}}{\cos{\left(x \right)}} = -1$$
o
$$- \sqrt{2} \tan{\left(x \right)} = -1$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en -sqrt(2)

La ecuación se convierte en
$$\tan{\left(x \right)} = - \frac{\sqrt{2}}{2}$$
Esta ecuación se reorganiza en
$$x = \pi n + \operatorname{atan}{\left(- \frac{\sqrt{2}}{2} \right)}$$
O
$$x = \pi n - \operatorname{atan}{\left(\frac{\sqrt{2}}{2} \right)}$$
, donde n es cualquier número entero
