Solución

Ha introducido [src]
cot(-x) = 1
$$\cot{\left(- x \right)} = 1$$
Solución detallada
Tenemos la ecuación
$$\cot{\left(- x \right)} = 1$$
cambiamos
$$- \cot{\left(x \right)} - 1 = 0$$
$$- \cot{\left(x \right)} - 1 = 0$$
Sustituimos
$$w = \cot{\left(x \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$- w = 1$$
Dividamos ambos miembros de la ecuación en -1
w = 1 / (-1)

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