Solución
Solución detallada
Se da la desigualdad:
$$\sin{\left(t \right)} < - \frac{2}{3}$$
Para resolver esta desigualdad primero hay que resolver la ecuación correspondiente:
$$\sin{\left(t \right)} = - \frac{2}{3}$$
Resolvemos:
Tenemos la ecuación
$$\sin{\left(t \right)} = - \frac{2}{3}$$
cambiamos
$$\sin{\left(t \right)} + \frac{2}{3} = 0$$
$$\sin{\left(t \right)} + \frac{2}{3} = 0$$
Sustituimos
$$w = \sin{\left(t \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$w = - \frac{2}{3}$$
Obtenemos la respuesta: w = -2/3
hacemos cambio inverso
$$\sin{\left(t \right)} = w$$
sustituimos w:

son puntos de cambio del signo de desigualdad en las soluciones.
Primero definámonos con el signo hasta el punto extremo izquierdo:
$$x_{0} < x_{68}$$
Consideremos, por ejemplo, el punto
$$x_{0} = x_{68} - \frac{1}{10}$$
=
$$-1979.9330994178 + - \frac{1}{10}$$
=
$$-1980.0330994178$$
lo sustituimos en la expresión
$$\sin{\left(t \right)} < - \frac{2}{3}$$
$$\sin{\left(t \right)} < - \frac{2}{3}$$
Entonces
$$x < -1979.9330994178$$
no se cumple
significa que una de las soluciones de nuestra ecuación será con:
$$x > -1979.9330994178 \wedge x < -1755.42056570047$$
Recibiremos otras soluciones de la desigualdad pasando al polo siguiente etc.
etc.

$$\sin{\left(t \right)} < - \frac{2}{3}$$
Para resolver esta desigualdad primero hay que resolver la ecuación correspondiente:
$$\sin{\left(t \right)} = - \frac{2}{3}$$
Resolvemos:
Tenemos la ecuación
$$\sin{\left(t \right)} = - \frac{2}{3}$$
cambiamos
$$\sin{\left(t \right)} + \frac{2}{3} = 0$$
$$\sin{\left(t \right)} + \frac{2}{3} = 0$$
Sustituimos
$$w = \sin{\left(t \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$w = - \frac{2}{3}$$
Obtenemos la respuesta: w = -2/3
hacemos cambio inverso
$$\sin{\left(t \right)} = w$$
sustituimos w:

son puntos de cambio del signo de desigualdad en las soluciones.
Primero definámonos con el signo hasta el punto extremo izquierdo:
$$x_{0} < x_{68}$$
Consideremos, por ejemplo, el punto
$$x_{0} = x_{68} - \frac{1}{10}$$
=
$$-1979.9330994178 + - \frac{1}{10}$$
=
$$-1980.0330994178$$
lo sustituimos en la expresión
$$\sin{\left(t \right)} < - \frac{2}{3}$$
$$\sin{\left(t \right)} < - \frac{2}{3}$$
sin(t) < -2/3
Entonces
$$x < -1979.9330994178$$
no se cumple
significa que una de las soluciones de nuestra ecuación será con:
$$x > -1979.9330994178 \wedge x < -1755.42056570047$$
