    Above is a question I need some help with. I can get to a certain point, but I can't get beyond.
    Can somebody with knowledge about this help?

    Cn = 3/2 Sa(nπ/2)e-(jnπ)/2
    That is where I get up to, but I don't know what to do from there.
    The answer given is: 0 and 3/(jnπ)

    You need to show your work. It looks like you differentiated instead of integrated when calculating the coefficients.
