Best ResponseYou've already chosen the best response.1d(sin(sin(sin(2x))))/dx=dsinu/du*du/dx u=sin(sin(2x)) and dsinu/du=cosu

Best ResponseYou've already chosen the best response.1And then you apply it once more but that gets too messy for me to type  bound to make a mistake. Hehe, hope my answer helped to some extent atleast; good luck!

Best ResponseYou've already chosen the best response.1you should be getting \[2 \cos (2 x) \cos (\sin (2 x)) \cos (\sin (\sin (2 x)))\]

Best ResponseYou've already chosen the best response.0Sam's correct! You should take derivative from RIGHT to left: ( sin2x )' = 2 cosx sin ( sin2x) ' = 2 cosx * cos ( sin2x ) sin [ sin ( sin2x)] ' = 2 cosx * cos ( sin2x ) * cos [ sin ( sin2x)] Just go step by step, you won't miss it :)
