Solución
Solución detallada
Tenemos la ecuación
$$\cot{\left(- 3 x \right)} = -1$$
cambiamos
$$1 - \cot{\left(3 x \right)} = 0$$
$$1 - \cot{\left(3 x \right)} = 0$$
Sustituimos
$$w = \cot{\left(3 x \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$- w = -1$$
Dividamos ambos miembros de la ecuación en -1
Obtenemos la respuesta: w = 1
hacemos cambio inverso
$$\cot{\left(3 x \right)} = w$$
sustituimos w:
$$\cot{\left(- 3 x \right)} = -1$$
cambiamos
$$1 - \cot{\left(3 x \right)} = 0$$
$$1 - \cot{\left(3 x \right)} = 0$$
Sustituimos
$$w = \cot{\left(3 x \right)}$$
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
$$\cot{\left(3 x \right)} = w$$
sustituimos w:
