cot(x) = -\/ 3 
$$\cot{\left(x \right)} = - \sqrt{3}$$
Solución detallada
Tenemos la ecuación
$$\cot{\left(x \right)} = - \sqrt{3}$$
cambiamos
$$\cot{\left(x \right)} - 1 + \sqrt{3} = 0$$
$$\cot{\left(x \right)} - 1 + \sqrt{3} = 0$$
Sustituimos
$$w = \cot{\left(x \right)}$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
-1 + w + sqrt3 = 0

Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$w + \sqrt{3} = 1$$
Dividamos ambos miembros de la ecuación en (w + sqrt(3))/w
w = 1 / ((w + sqrt(3))/w)

Obtenemos la respuesta: w = 1 - sqrt(3)
hacemos cambio inverso
$$\cot{\left(x \right)} = w$$
sustituimos w:
