5*tan(x) - 8*cot(x) + 6 = 0
$$\left(5 \tan{\left(x \right)} - 8 \cot{\left(x \right)}\right) + 6 = 0$$
Respuesta rápida
[src]
x1 = atan(4/5)
$$x_{1} = \operatorname{atan}{\left(\frac{4}{5} \right)}$$
x2 = -atan(2)
$$x_{2} = - \operatorname{atan}{\left(2 \right)}$$
x2 = -atan(2)
Suma y producto de raíces
[src]
suma
atan(4/5) - atan(2)
$$- \operatorname{atan}{\left(2 \right)} + \operatorname{atan}{\left(\frac{4}{5} \right)}$$
=
-atan(2) + atan(4/5)
$$- \operatorname{atan}{\left(2 \right)} + \operatorname{atan}{\left(\frac{4}{5} \right)}$$
producto
atan(4/5)*(-atan(2))
$$\operatorname{atan}{\left(\frac{4}{5} \right)} \left(- \operatorname{atan}{\left(2 \right)}\right)$$
=
-atan(2)*atan(4/5)
$$- \operatorname{atan}{\left(\frac{4}{5} \right)} \operatorname{atan}{\left(2 \right)}$$
-atan(2)*atan(4/5)
