2 f(x) = -1 - x - cos(2*x) - sin(2*x) + x*(-1 - cos(2*x) - sin(2*x))
$$f{\left(x \right)} = x \left(\left(- \cos{\left(2 x \right)} - 1\right) - \sin{\left(2 x \right)}\right) + \left(\left(\left(- x^{2} - 1\right) - \cos{\left(2 x \right)}\right) - \sin{\left(2 x \right)}\right)$$
f = x*(-cos(2*x) - 1 - sin(2*x)) - x^2 - 1 - cos(2*x) - sin(2*x)
Gráfico de la función
Puntos de cruce con el eje de coordenadas X
El gráfico de la función cruce el eje X con f = 0
o sea hay que resolver la ecuación:
$$x \left(\left(- \cos{\left(2 x \right)} - 1\right) - \sin{\left(2 x \right)}\right) + \left(\left(\left(- x^{2} - 1\right) - \cos{\left(2 x \right)}\right) - \sin{\left(2 x \right)}\right) = 0$$
Resolvermos esta ecuación
Solución no hallada,
puede ser que el gráfico no cruce el eje X
o sea hay que resolver la ecuación:
$$x \left(\left(- \cos{\left(2 x \right)} - 1\right) - \sin{\left(2 x \right)}\right) + \left(\left(\left(- x^{2} - 1\right) - \cos{\left(2 x \right)}\right) - \sin{\left(2 x \right)}\right) = 0$$

Solución no hallada,
puede ser que el gráfico no cruce el eje X
Extremos de la función
Para hallar los extremos hay que resolver la ecuación
$$\frac{d}{d x} f{\left(x \right)} = 0$$
(la derivada es igual a cero),
y las raíces de esta ecuación serán los extremos de esta función:
$$\frac{d}{d x} f{\left(x \right)} = $$
primera derivada
$$x \left(2 \sin{\left(2 x \right)} - 2 \cos{\left(2 x \right)}\right) - 2 x + \sin{\left(2 x \right)} - 3 \cos{\left(2 x \right)} - 1 = 0$$

Puntos de flexiones
Hallemos los puntos de flexiones, para eso hay que resolver la ecuación
$$\frac{d^{2}}{d x^{2}} f{\left(x \right)} = 0$$
(la segunda derivada es igual a cero),
las raíces de la ecuación obtenida serán los puntos de flexión para el gráfico de la función indicado:
$$\frac{d^{2}}{d x^{2}} f{\left(x \right)} = $$
segunda derivada
$$2 \left(2 x \left(\sin{\left(2 x \right)} + \cos{\left(2 x \right)}\right) + 4 \sin{\left(2 x \right)} - 1\right) = 0$$
