Which trigonometric function is an odd function and why? A) The sine function is odd because it is represented by the y-coordinate of the points on the unit circle, and therefore sin(-x) = - sin(x).

B) The cosine function is odd because it is represented by the r-coordinate of the points on the unit circle, and therefore cos(-x) = – cos(z).

C) The cosine function is odd because it is represented by the r-coordinate of the points on the unit circle, and therefore cos(x) = cos(-2).

D) The sine function is odd because it is represented by the y-coordinate of the points on the unit circle, and therefore sin() = sin(-x).
