Solución

Ha introducido [src]
sin(x)*(x + 1) = 0
$$\left(x + 1\right) \sin{\left(x \right)} = 0$$
Solución detallada
Tenemos la ecuación
$$\left(x + 1\right) \sin{\left(x \right)} = 0$$
cambiamos
$$\left(x + 1\right) \sin{\left(x \right)} = 0$$
$$\left(x + 1\right) \sin{\left(x \right)} = 0$$
Sustituimos
$$w = \sin{\left(x \right)}$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
wx+1 = 0

Dividamos ambos miembros de la ecuación en 1 + x
w = 0 / (1 + 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:
$$x_{1} = 2 \pi n + \operatorname{asin}{\left(w_{1} \right)}$$
$$x_{1} = 2 \pi n + \operatorname{asin}{\left(0 \right)}$$
$$x_{1} = 2 \pi n$$
$$x_{2} = 2 \pi n - \operatorname{asin}{\left(w_{1} \right)} + \pi$$
$$x_{2} = 2 \pi n - \operatorname{asin}{\left(0 \right)} + \pi$$
$$x_{2} = 2 \pi n + \pi$$
