Solución
Ha introducido
[src]
2*sin(x) - 3*cos(x) - 2 = 0
$$\left(2 \sin{\left(x \right)} - 3 \cos{\left(x \right)}\right) - 2 = 0$$
Suma y producto de raíces
[src]
suma
pi -- - 2*atan(5) 2
$$- 2 \operatorname{atan}{\left(5 \right)} + \frac{\pi}{2}$$
=
pi -- - 2*atan(5) 2
$$- 2 \operatorname{atan}{\left(5 \right)} + \frac{\pi}{2}$$
producto
pi --*-2*atan(5) 2
$$\frac{\pi}{2} \left(- 2 \operatorname{atan}{\left(5 \right)}\right)$$
=
-pi*atan(5)
$$- \pi \operatorname{atan}{\left(5 \right)}$$
-pi*atan(5)
Respuesta rápida
