Solución
Ha introducido
[src]
sin(2*x) - cos(x) + 2*sin(x) = 1
$$\left(\sin{\left(2 x \right)} - \cos{\left(x \right)}\right) + 2 \sin{\left(x \right)} = 1$$
Suma y producto de raíces

suma
pi 5*pi -- + ---- + pi 6 6
$$\left(\frac{\pi}{6} + \frac{5 \pi}{6}\right) + \pi$$
=
2*pi
$$2 \pi$$
producto
pi 5*pi --*----*pi 6 6
$$\pi \frac{\pi}{6} \frac{5 \pi}{6}$$
=
