Question 1161752
<br>
An angle of 11pi/6 is just short of 2pi = 12pi/6, so you are just short of a full revolution counterclockwise from 2pi, which is coterminal with 0.<br>
So you are in the fourth quadrant, where x is positive and y is negative.<br>
Sine is the y value, so sin(11pi/6) is negative.<br>
ANSWER: negative<br>
