$$\frac{\left(\left(2 \sin^{2}{\left(x \right)} + 1\right) + 2 \sin{\left(x \right)}\right) + 2 \sin{\left(x \right)} \cos{\left(x \right)}}{2 \sin{\left(x \right)} \cos{\left(x \right)} - 1} = 1$$
Solución detallada
Tenemos la ecuación
$$\frac{\left(\left(2 \sin^{2}{\left(x \right)} + 1\right) + 2 \sin{\left(x \right)}\right) + 2 \sin{\left(x \right)} \cos{\left(x \right)}}{2 \sin{\left(x \right)} \cos{\left(x \right)} - 1} = 1$$
cambiamos
$$\frac{2 \left(\sin^{2}{\left(x \right)} + \sin{\left(x \right)} + 1\right)}{\sin{\left(2 x \right)} - 1} = 0$$
$$-1 + \frac{\left(\left(2 \sin^{2}{\left(x \right)} + 1\right) + 2 \sin{\left(x \right)}\right) + 2 \sin{\left(x \right)} \cos{\left(x \right)}}{2 \sin{\left(x \right)} \cos{\left(x \right)} - 1} = 0$$
Sustituimos
$$w = \cos{\left(x \right)}$$
Tenemos la ecuación:
$$-1 + \frac{2 w \sin{\left(x \right)} + 2 \sin^{2}{\left(x \right)} + 2 \sin{\left(x \right)} + 1}{2 w \sin{\left(x \right)} - 1} = 0$$
Multipliquemos las dos partes de la ecuación por el denominador -1 + 2*w*sin(x)
obtendremos:
$$2 \sin^{2}{\left(x \right)} + 2 \sin{\left(x \right)} + 2 = 0$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
2 + 2*sinx^2 + 2*sinx = 0

Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$2 \sin^{2}{\left(x \right)} + 2 \sin{\left(x \right)} = -2$$
Esta ecuación no tiene soluciones
hacemos cambio inverso
$$\cos{\left(x \right)} = w$$
Tenemos la ecuación
$$\cos{\left(x \right)} = w$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$x = \pi n + \operatorname{acos}{\left(w \right)}$$
$$x = \pi n + \operatorname{acos}{\left(w \right)} - \pi$$
O
$$x = \pi n + \operatorname{acos}{\left(w \right)}$$
$$x = \pi n + \operatorname{acos}{\left(w \right)} - \pi$$
, donde n es cualquier número entero
sustituimos w:
