Extrapolated Faá Di Bruno's Formula - Xorter - 11/19/2016
Here is how to evaluate the nth derivative of f o g:

My question is that: Is it possible to get a formula for integrate f o g dx? Where integrating means the -1st derivative.
Can we extrapolate this formula to the negative numbers?

What if I say the next:
N=-1
int f o g dx = ?
-1b[-1] = -1
b[-1] = 1
k = 1
int f o g dx = (-1)!/1! f' o g * (g^(-1)/(-1)!)^1 = f' o g * int g dx
But it does not work ... Why?
