It should be -pi/6 but apparently that isn't right.....
OpenStudy (paxpolaris):
maybe the answer is supposed to be in degrees ... so -30deg or if you are given the range of the angle ... it could also be 150deg, or 330deg
OpenStudy (konradzuse):
it just said evaluate the expression without using a calculator... he last one was pi/3 for arccos(1/2)
OpenStudy (paxpolaris):
maybe the angle has to be between 0 and pi, try 5pi/6|dw:1340310531072:dw|
