$$- \frac{\sin{\left(x \right)}}{\sqrt{2}} + \frac{\cos{\left(x \right)}}{\sqrt{2}} = 0$$
Solución detallada
Tenemos la ecuación
$$- \frac{\sin{\left(x \right)}}{\sqrt{2}} + \frac{\cos{\left(x \right)}}{\sqrt{2}} = 0$$
cambiamos:
$$- \frac{\sqrt{2} \sin{\left(x \right)}}{2 \cos{\left(x \right)}} = - \frac{\sqrt{2}}{2}$$
o
$$- \frac{\sqrt{2} \tan{\left(x \right)}}{2} = - \frac{\sqrt{2}}{2}$$
es la ecuación trigonométrica más simple
La ecuación se convierte en
$$\tan{\left(x \right)} = -1$$
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
$$- \frac{\sin{\left(x \right)}}{\sqrt{2}} + \frac{\cos{\left(x \right)}}{\sqrt{2}} = 0$$
cambiamos:
$$- \frac{\sqrt{2} \sin{\left(x \right)}}{2 \cos{\left(x \right)}} = - \frac{\sqrt{2}}{2}$$
o
$$- \frac{\sqrt{2} \tan{\left(x \right)}}{2} = - \frac{\sqrt{2}}{2}$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en -sqrt(2)/2
La ecuación se convierte en
$$\tan{\left(x \right)} = -1$$
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
