Final answer:
The sine of -π/3 is -√3/2, because the sine function is odd, inverting the sign when the angle is negative.
Step-by-step explanation:
The question asks to evaluate the sine of - π/3. The special angle π/3 corresponds to 60 degrees, and the sine of 60 degrees is √3/2. However, the sine function is an odd function, which means that sin(-θ) = -sin(θ). Therefore, the sine of -π/3 is the negative of the sine of π/3.
The correct answer is B) -√3/2.
