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