Question 532411: Explain why sin 3 (degrees) + sin 357 (degress) = 0?
Answer by richard1234(7193) (Show Source): You can put this solution on YOUR website!
For a given point on the unit circle, the x-coordinate represents the cosine of the angle and the y-coordinate represents the sine of the angle. If you were to draw the points corresponding to "arguments" of 3 degrees and 357 degrees, you would see that their y-coordinates are inverses of each other (one is +a, another is -a). The y-coordinates correspond to the sine of the angle, so sin 3 + sin 357 = 0.
