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