cot(x) = -----
           ___
         \/ 2 
$$\cot{\left(x \right)} = \frac{1}{\sqrt{2}}$$
Solución detallada
Tenemos la ecuación
$$\cot{\left(x \right)} = \frac{1}{\sqrt{2}}$$
cambiamos
$$\cot{\left(x \right)} - 1 - \frac{\sqrt{2}}{2} = 0$$
$$\cot{\left(x \right)} - 1 - \frac{\sqrt{2}}{2} = 0$$
Sustituimos
$$w = \cot{\left(x \right)}$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
-1 + w - sqrt2/2 = 0

Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$w - \frac{\sqrt{2}}{2} = 1$$
Dividamos ambos miembros de la ecuación en (w - sqrt(2)/2)/w
w = 1 / ((w - sqrt(2)/2)/w)

Obtenemos la respuesta: w = 1 + sqrt(2)/2
hacemos cambio inverso
$$\cot{\left(x \right)} = w$$
sustituimos w:
