TRIGONOMETRIA Esempio N°2 Consideriamo un triangolo rettangolo con un angolo α = 30°, quindi l’altro angolo β = 60°; salve,ho una invalidita di 60%.cosa mi spetta economicamente?avendo finanziamento in corso,cosa si puo ottenere? ho 36 anni con 17 anni di lavoro.grazie Rispondi koffi likolo 2 ottobre 2019 at 17:27 L'ascissa x e l'ordinata y di questo punto sono uguali rispettivamente a cos θ e sin θ. Il triangolo nel disegno dimostra l'equivalenza con la definizione precedente: il raggio della circonferenza è l'ipotenusa del triangolo ed ha una lunghezza pari ad 1, pertanto sin θ = y/1 e cos θ = x/1.
