Best ResponseYou've already chosen the best response.0try replacing tan(4 pi x) with u so you have 2(u)^3 then use the chain rule from there

Best ResponseYou've already chosen the best response.0ok i got: 1/2 x^2{(16x^2)^1/2(2x)}+(16x^2)^1/2 (x)

Best ResponseYou've already chosen the best response.0to differentiate 2(u)^3 with respect to u, you just need to use the power rule so it becomes 6u^2
