Determine all solutions of the equation in radians.
Find cos x/2 , given that cos x =1/4 and x terminates in 0 < x < pi/2
~~~~~~~~~~~~~~~~~~~~~~~~

cosx%2F2%29 = sqrt%28%281%2Bcos%28x%29%29%2F2%29 = sqrt%281+%2B+1%2F4%29 = sqrt%285%2F4%29 = sqrt%285%29%2F2.

The sign is "+".

By the way, the first line of the condition is not relevant to its second line.
There is no any equation in this problem.
Watch your language.
