Extrapolated Faá Di Bruno's Formula Xorter Fellow Posts: 93 Threads: 30 Joined: Aug 2016 11/19/2016, 02:07 PM Here is how to evaluate the nth derivative of f o g: https://en.wikipedia.org/wiki/Faà_di_Bru...orial_form http://www.maa.org/sites/default/files/i...17-234.pdf 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?
