    f(x) = e^(2pix)

    f(x)= x^(e2pi)

    f(x)= (epi)^2x

    i'll try the first one....
    f(x) = e^{(2pix)}
    you can find the f'(x) with chain rule method, and remember this one
    f(x) = e^{x}
    f'(x) = e^{x}
    so, f'(x) =(2) (pi) e^{(2pix)}

    Or,

    f(x) = e^{ax}
    f'(x) = a e^{ax}

    and the power rule:

    f(x) = x^{a}
    f'(x) = a x^{a-1}
