The base of the pyramid AOBC is an equilateral triangle OBC with each side equal to 4 
. ' O ' is the origin of reference, AO is perpendicular to the plane of Δ OBC and 
= 2 . Then find the cosine of the angle between the skew straight lines one passing through A and the mid point of OB and the other passing through 'O' and the mid point of BC.
