Explain why sine of an angle greater than 180° and less than 360° is negative.
1 answer:
9514 1404 393
Explanation:
The sine of an angle in standard position is the y-coordinate of the intersection of its terminal ray with the unit circle. When the angle is in the range 180° < θ < 360°, that point of intersection is in quadrant III or IV, where y-coordinates are negative.

<em>Alternative explanation</em>:
That is where the sine curve is below the x-axis.
