For compositions,
I thought u substitution.
So change x out now, save it for the solution.

Oh, you got d - y - d - x is
I know It’s just d - y - d - u,
times d - u - d - x,
Oh respect this Chain Rule

Chain chain chain…
Chain Rule.
Chain chain chain…
Chain Rule.

Every chain, has got one more link,
For each composition, but don’t lose your strength.

Oooh, babe (Woo, woo, woo, woo)
You gotta see the function alone! (Ooo, ooo, ooo, ooo)
Don’t matter what’s inside it at all! (Ooo, ooo, ooo, ooo)
Take the Derivative, take it easy!
Oh don’t change its insides just you clone and now apply the:
Chain, chain, chain…
Chain Rule.
Chain, chain, chain…
Chain Rule.
Oh, we are not finished,
we still gotta take,
derivative of inside,
and multiply all I can babe!

Chain, chain, chain…
Chain Rule.
Chain, chain, chain…
Chain Rule.
