cot(3*x - 1)    
------------ = 0
     x          
$$\frac{\cot{\left(3 x - 1 \right)}}{x} = 0$$
Solución detallada
Tenemos la ecuación
$$\frac{\cot{\left(3 x - 1 \right)}}{x} = 0$$
cambiamos
$$\frac{- x + \cot{\left(3 x - 1 \right)}}{x} = 0$$
$$-1 + \frac{\cot{\left(3 x - 1 \right)}}{x} = 0$$
Sustituimos
$$w = \cot{\left(3 x - 1 \right)}$$
Tenemos la ecuación:
$$-1 + \frac{\cot{\left(3 x - 1 \right)}}{x} = 0$$
Usamos la regla de proporciones:
De a1/b1 = a2/b2 se deduce a1*b2 = a2*b1,
En nuestro caso
a1 = cot(-1 + 3*x)

b1 = x

a2 = 1

b2 = 1

signo obtendremos la ecuación
$$\cot{\left(3 x - 1 \right)} = x$$
$$\cot{\left(3 x - 1 \right)} = x$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
cot-1+3*x = x

Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$\cot{\left(3 x - 1 \right)} + 1 = x + 1$$
Esta ecuación no tiene soluciones
hacemos cambio inverso
$$\cot{\left(3 x - 1 \right)} = w$$
sustituimos w:
