I also need help to determine suppement of 5pi/12 and complement of 3pi/8. I am looking at my book and teacher's notes and I don't see it explained at all. Thanks so kindly for your time.Found 2 solutions by stanbon, Alan3354:Answer by stanbon(57397)   (Show Source): You can put this solution on YOUR website!Find 2 real #'s between -2pi and 2pi that determine the point on the unit circle. --- You have give us some information about the point. ============================================================= I know 1 time around the unit circle is 2pi and one time around the unit circle clockwise is -2pi. =========================== I also need help to determine supplement of 5pi/12 --- Ans: 2pi - (5/12)pi = (24/12)pi-(5/12)pi = (19/12)pi ======================================================= The complement of 3pi/8 --- Ans: (1/2)pi - (3/8)pi = (4/8)pi - (3/8)pi --- = (1/8)pi ============== Cheers, Stan H. Answer by Alan3354(30993)   (Show Source): You can put this solution on YOUR website!I also need help to determine suppement of 5pi/12 and complement of 3pi/8 ------ Supplement of 5pi/12 = 12pi/12 - 5pi/12 = 7pi/12 --------- Complement of 3pi/8 = 4pi/8 - 3pi/8 = pi/8
