The discussion clarifies that $$\sin(120^\circ)$$ is equal to $$\sin(60^\circ)$$, which is a fundamental concept in trigonometry. This equality arises from the properties of the unit circle, where angles are measured in radians and their sine values correspond to the y-coordinates of points on the circle. The confusion regarding the addition of sine values is addressed, emphasizing that $$\sin(120^\circ)$$ does not equal $$\sin(60^\circ) + \sin(60^\circ)$$ but rather directly corresponds to the sine of the reference angle.
