anyone know how to approach these?? i've tried cal. the derivatives but they just keep getting more complex, and i don't see any resemblance between them to get a formula for the nth derivative.....

Blues' hint for 11.5... use something that you already know the expansion for.
i) let g(u) = cos(u)
find the expansion for that
plug in u=x^2 and multiply the entire thing by x
ii) let g(u) = e^u
and do the same thing
