We have: $\sin(30^{\circ} + 60^{\circ})$ = $\sin 30^{\circ}$ + $\sin 60^{\circ}$ The questions becomes if the below statement is true. $\sin 90^{\circ}$ = $\sin 30^{\circ}$ + $\sin 60^{\circ}$ To break this down, we calculate each function separately. $\sin 30^{\circ}$ = $\frac{1}{2}$ $\sin 60^{\circ}$ = $\frac{\sqrt 3}{2}$ $\sin 90^{\circ}$ = 1 Is the following true? 1 = $\frac{1}{2}$ + $\frac{\sqrt 3}{2}$ 1 = 1.37 The answer becomes FALSE.
