    From A to B is just the simplification of taking the limits of integration, in the case, from 0 to pi.


    To help you understand part C, fill in a table of what cos(2*n*pi - pi) will give you for different values of n...

    Hi, thanks for the reply.

    Ok I did the table and noticed that whatever the value of n is, the answer will still remain -1.

    Regarding step B, I still cannot understand from where the "-1"s and the minus in front came from...

    Hi again,

    Attached is a photo showing how I worked step B. Is it correct please? since I end up not using -1 (which I don't know from where it came from)
