Answer by greenestamps(13203) (Show Source): You can put this solution on YOUR website!
The real part is negative and the imaginary part is positive, so the complex number is in quadrant II.
The magnitude is
The reference angle is = 30 degrees or pi/6 radians. A reference angle of pi/6 radians in quadrant II means the angle is 5pi/6.
The magnitude is 2; the angle is 5pi/6. So
ANSWER: B. 2(cos5pi/6 + isin5pi/6)
