Solución detallada
Tenemos la ecuación
$$\frac{\tan{\left(x \right)} \operatorname{atan}{\left(\frac{1}{x - 2} \right)}}{x} = 0$$
cambiamos
$$\frac{- x + \tan{\left(x \right)} \operatorname{atan}{\left(\frac{1}{x - 2} \right)}}{x} = 0$$
$$-1 + \frac{\tan{\left(x \right)} \operatorname{atan}{\left(\frac{1}{x - 2} \right)}}{x} = 0$$
Sustituimos
$$w = \operatorname{atan}{\left(\frac{1}{x - 2} \right)}$$
Tenemos la ecuación:
$$-1 + \frac{\tan{\left(x \right)} \operatorname{atan}{\left(\frac{1}{x - 2} \right)}}{x} = 0$$
Usamos la regla de proporciones:
De a1/b1 = a2/b2 se deduce a1*b2 = a2*b1,
En nuestro caso
a1 = atan(1/(-2 + x))*tan(x)

b1 = x

a2 = 1

b2 = 1

signo obtendremos la ecuación
$$\tan{\left(x \right)} \operatorname{atan}{\left(\frac{1}{x - 2} \right)} = x$$
$$\tan{\left(x \right)} \operatorname{atan}{\left(\frac{1}{x - 2} \right)} = x$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
atan1/-2+x)*tanx = x

Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$\tan{\left(x \right)} \operatorname{atan}{\left(\frac{1}{x - 2} \right)} + 2 = x + 2$$
Esta ecuación no tiene soluciones
hacemos cambio inverso
$$\operatorname{atan}{\left(\frac{1}{x - 2} \right)} = w$$
sustituimos w:
