\x  - 3*x/*(-sin(x)) = 0
$$\left(x^{2} - 3 x\right) \left(- \sin{\left(x \right)}\right) = 0$$
Solución detallada
Tenemos la ecuación
$$\left(x^{2} - 3 x\right) \left(- \sin{\left(x \right)}\right) = 0$$
cambiamos
$$x \left(3 - x\right) \sin{\left(x \right)} = 0$$
$$\left(x^{2} - 3 x\right) \left(- \sin{\left(x \right)}\right) = 0$$
Sustituimos
$$w = \sin{\left(x \right)}$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
-wx+2+3*x = 0

Dividamos ambos miembros de la ecuación en -x^2 + 3*x
w = 0 / (-x^2 + 3*x)

Obtenemos la respuesta: w = 0
hacemos cambio inverso
$$\sin{\left(x \right)} = w$$
Tenemos la ecuación
$$\sin{\left(x \right)} = w$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$x = 2 \pi n + \operatorname{asin}{\left(w \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(w \right)} + \pi$$
O
$$x = 2 \pi n + \operatorname{asin}{\left(w \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(w \right)} + \pi$$
, donde n es cualquier número entero
sustituimos w:
$$x_{1} = 2 \pi n + \operatorname{asin}{\left(w_{1} \right)}$$
$$x_{1} = 2 \pi n + \operatorname{asin}{\left(0 \right)}$$
$$x_{1} = 2 \pi n$$
$$x_{2} = 2 \pi n - \operatorname{asin}{\left(w_{1} \right)} + \pi$$
$$x_{2} = 2 \pi n - \operatorname{asin}{\left(0 \right)} + \pi$$
$$x_{2} = 2 \pi n + \pi$$
