Question3) semplifica l'espressione usando le proprietà degli angoli associati (indica l'angolo a e gli altri 2 angoli sulla circonferenza goniometrica) 3sin(2πα)cosαsin(32π+α)3 \sin (2 \pi-\alpha)-\frac{\cos \alpha}{\sin \left(\frac{3}{2} \pi+\alpha\right)}

Studdy Solution
Combinare i risultati ottenuti:
3sin(α)(1)=3sin(α)+1 -3\sin(\alpha) - (-1) = -3\sin(\alpha) + 1
L'espressione semplificata è:
3sin(α)+1 \boxed{-3\sin(\alpha) + 1}
