    try replacing tan(4 pi x) with u so you have 2(u)^3 then use the chain rule from there

    ok i got: 1/2 x^2{(16-x^2)^-1/2(2x)}+(16-x^2)^-1/2 (x)

    the first step is to differentiate 2(u)^3 with respect to u

    to differentiate 2(u)^3 with respect to u, you just need to use the power rule so it becomes 6u^2
