Question

?14% Part (a) It is sometimes convenient to specify a point on the unit circle using a reference angle. A reference angle is measured from the x axis in a manner that produces the smallest value in $\theta \in [0, \frac{\pi}{2}]$. Whether it is measured clockwise or counterclockwise, and whether it is measured from the positive or negative x axis, depends upon the quadrant. Which image below represents the correct definition of the reference angle for quadrant I?
