sin (3*x) = 0
$$\sin^{4}{\left(3 x \right)} = 0$$
Solución detallada
Tenemos la ecuación
$$\sin^{4}{\left(3 x \right)} = 0$$
cambiamos
$$\sin^{4}{\left(3 x \right)} = 0$$
$$\sin^{4}{\left(3 x \right)} = 0$$
Sustituimos
$$w = \sin{\left(3 x \right)}$$
Tenemos la ecuación
$$w^{4} = 0$$
es decir
$$w = 0$$
Obtenemos la respuesta: w = 0
hacemos cambio inverso
$$\sin{\left(3 x \right)} = w$$
Tenemos la ecuación
$$\sin{\left(3 x \right)} = w$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$3 x = 2 \pi n + \operatorname{asin}{\left(w \right)}$$
$$3 x = 2 \pi n - \operatorname{asin}{\left(w \right)} + \pi$$
O
$$3 x = 2 \pi n + \operatorname{asin}{\left(w \right)}$$
$$3 x = 2 \pi n - \operatorname{asin}{\left(w \right)} + \pi$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$3$$
sustituimos w:
$$x_{1} = \frac{2 \pi n}{3} + \frac{\operatorname{asin}{\left(w_{1} \right)}}{3}$$
$$x_{1} = \frac{2 \pi n}{3} + \frac{\operatorname{asin}{\left(0 \right)}}{3}$$
$$x_{1} = \frac{2 \pi n}{3}$$
$$x_{2} = \frac{2 \pi n}{3} - \frac{\operatorname{asin}{\left(w_{1} \right)}}{3} + \frac{\pi}{3}$$
$$x_{2} = \frac{2 \pi n}{3} - \frac{\operatorname{asin}{\left(0 \right)}}{3} + \frac{\pi}{3}$$
$$x_{2} = \frac{2 \pi n}{3} + \frac{\pi}{3}$$
