Solución

Ha introducido [src]
3*sin(x) + 4*cos(x) = 0
$$3 \sin{\left(x \right)} + 4 \cos{\left(x \right)} = 0$$
Solución detallada
Tenemos la ecuación
$$3 \sin{\left(x \right)} + 4 \cos{\left(x \right)} = 0$$
cambiamos:
$$\frac{3 \sin{\left(x \right)}}{\cos{\left(x \right)}} = -4$$
o
$$3 \tan{\left(x \right)} = -4$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en 3

La ecuación se convierte en
$$\tan{\left(x \right)} = \frac{4}{3}$$
Esta ecuación se reorganiza en
$$x = \pi n + \operatorname{atan}{\left(\frac{4}{3} \right)}$$
O
$$x = \pi n + \operatorname{atan}{\left(\frac{4}{3} \right)}$$
, donde n es cualquier número entero
