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

Choice A) Odd

The function sin(x) is odd because sin(-x) = -sin(x) for all values of x

As the example shows, sin(150) = 0.5 and sin(-150) = -0.5, so this shows sin(-150) = -sin(150).
