WebYou can use the trig identity for the sine of a difference of angles, sin (A−B), to convert the expression to a form that contains just sines and cosines of special angles. From this, you can simplify to get the exact form of the sine's value. (Fifteen is also half of thirty, and 30° is one of the special angles.
