The fact that sin(150°) = .5 and sin(-150°) = -.5 implies that the sine function is which type of function?
A) odd
B) even
C) neither
D) cannot be determined
In general, sin(-x) = -sin(x) for all values of x, so it's an odd function. I don't mean it's a strange function. I mean "odd" in the sense that it's not even (eg: the number 7 is an odd number).
