Try the substitution . Whats the reasoning behind this?
Oh nvm thanks Nacho!
k so I have where do I go from that? Sorry if i dont respond right away, my laptops about to die and I have a chemistry seminar for the next hour just been trying to get some math done while I wait
You should get after the substitution.

You should get after the substitution. Isn't it after the substitution? Cuz the derivative of 16tan(u) = (16sec(u))^2 ?
Now factor the denominator and use the identity
256=16^2 is the reasoning(correct me if i am wrong!).
k alright, after that I have...
i guess can you just sqrt the sec(U)^2? that would make this pretty easy then
And now I'm utterly lost how to sub back u in... I would assume u=tan^(-1)(x)/(16)... but what do I do with something like that...? This question looked so harmless to begin with...
