Best ResponseYou've already chosen the best response.0Not sure I understand the question, but this is what I think: Take the inverse cosine==> cos^1(0.0623) then add 90deg or pi/2(if your problem is in radians) until you go all the way around the unit circle. So if you problem is in radians you should get 1.633,3.203,4.774, 6.345

Best ResponseYou've already chosen the best response.0you take the cosine inverse to determine the angle. Which will spit out an angle in the top half of the circle; swing down to get the other one...

Best ResponseYou've already chosen the best response.0when i take the inverse cos, i get 93.... which is not between 0 and 2pi

Best ResponseYou've already chosen the best response.0Oh, amistre64 is right, you should add 180deg (pi) not pi/2...sorry just saw that, you should get 1.633 and 4.774 only, my bad
