Answer:
Step-by-step explanation:
The given function is
[tex]sin(\frac{3 \pi}{2} )[/tex]
Where [tex]\pi = 180 \°[/tex], so the angle is [tex]\frac{3(180)}{2}=270[/tex]
This angle is at between the third and fourth quadrant, the angle has its endside at y-axis, specifically, at its negative side, where the sin function is -1, because it's in the negative part of y-axis.
Therefore, the right answer is negative.
