Solución
Ha introducido
[src]
sin(3*x) - cos(3*x) = 0
$$\sin{\left(3 x \right)} - \cos{\left(3 x \right)} = 0$$
Solución detallada
Tenemos la ecuación
$$\sin{\left(3 x \right)} - \cos{\left(3 x \right)} = 0$$
cambiamos:
$$\frac{\sin{\left(3 x \right)}}{\cos{\left(3 x \right)}} = 1$$
o
$$\tan{\left(3 x \right)} = 1$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$3 x = \pi n + \operatorname{atan}{\left(-1 \right)}$$
O
$$3 x = \pi n - \frac{\pi}{4}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$3$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n}{3} - \frac{\pi}{12}$$
$$\sin{\left(3 x \right)} - \cos{\left(3 x \right)} = 0$$
cambiamos:
