Oui, -5π/6 appartient au domaine de définition [-3π ; 3π] Voici pourquoi: Le domaine [-3π; 3π] représente un intervalle fermé, ce qui signifie qu'il inclut tous les nombres réels de -3π (inclus) à 3π (inclus). -5π/6 est un nombre réel. Il se situe entre -3π et 3π sur le cercle unité. Par conséquent, -5π/6 satisfait à la condition d’être dans l’intervalle fermé défini par le domaine [-3π ; 3π].
