Solución
Solución detallada
Tenemos la ecuación
$$\cot{\left(x \right)} = \frac{19}{15}$$
cambiamos
$$\cot{\left(x \right)} - \frac{19}{15} = 0$$
$$\cot{\left(x \right)} - \frac{19}{15} = 0$$
Sustituimos
$$w = \cot{\left(x \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$w = \frac{19}{15}$$
Obtenemos la respuesta: w = 19/15
hacemos cambio inverso
$$\cot{\left(x \right)} = w$$
sustituimos w:
$$\cot{\left(x \right)} = \frac{19}{15}$$
cambiamos
$$\cot{\left(x \right)} - \frac{19}{15} = 0$$
$$\cot{\left(x \right)} - \frac{19}{15} = 0$$
Sustituimos
$$w = \cot{\left(x \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$w = \frac{19}{15}$$
Obtenemos la respuesta: w = 19/15
hacemos cambio inverso
$$\cot{\left(x \right)} = w$$
sustituimos w:
