En la desigualdad la incógnita

Solución

Ha introducido [src]
sin(t) < 0
sin(t)<0\sin{\left(t \right)} < 0
sin(t) < 0
Solución detallada
Se da la desigualdad:
sin(t)<0\sin{\left(t \right)} < 0
Para resolver esta desigualdad primero hay que resolver la ecuación correspondiente:
sin(t)=0\sin{\left(t \right)} = 0
Resolvemos:
Tenemos la ecuación
sin(t)=0\sin{\left(t \right)} = 0
cambiamos
sin(t)1=0\sin{\left(t \right)} - 1 = 0
sin(t)1=0\sin{\left(t \right)} - 1 = 0
Sustituimos
w=sin(t)w = \sin{\left(t \right)}
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
w=1w = 1
Obtenemos la respuesta: w = 1
hacemos cambio inverso
sin(t)=w\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:
x0<x23x_{0} < x_{23}
Consideremos, por ejemplo, el punto
x0=x23110x_{0} = x_{23} - \frac{1}{10}
=
2642.07942166902+110-2642.07942166902 + - \frac{1}{10}
=
2642.17942166902-2642.17942166902
lo sustituimos en la expresión
sin(t)<0\sin{\left(t \right)} < 0
sin(t)<0\sin{\left(t \right)} < 0
sin(t) < 0

Entonces
x<2642.07942166902x < -2642.07942166902
no se cumple
significa que una de las soluciones de nuestra ecuación será con:
x>2642.07942166902x<267.035375555132x > -2642.07942166902 \wedge x < -267.035375555132
