    Here the question is simply Cos(2x)csc(2x)- cos(2x) using trigonometry identities.

    We know that Csc(x)= 1/ sin(x) , since Csc(2x)= 1/ sin(2x) , Now plug this into the given expression.

    Step :1

    So, Cos(2x)csc(2x)- cos(2x) = cos(2x) (1/sin(2x) ) - cos(2x)

    Step:2 = cos(2x)
    ______ - cos(2x) [ cos(x)/ sin(x) = cot(x) ]
    sin(2x)

    = cot(2x) - cos(2x)

    We cannot simplify this further , If we simplify this further again we will get the given expression.

    So, Cos(2x)csc(2x) - cos(2x)= cot(2x) - cos (2x)
