Solución
Solución detallada
Tenemos la ecuación
$$\sin{\left(x \right)} = \cos{\left(x \right)}$$
cambiamos:
$$\frac{\sin{\left(x \right)}}{\cos{\left(x \right)}} = 1$$
o
$$\tan{\left(x \right)} = 1$$
es la ecuación trigonométrica más simple
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
