Algoritmization of parametric derivation Xorter Fellow Posts: 81 Threads: 26 Joined: Aug 2016 04/12/2017, 02:29 PM I have a really strange f function (that I would like to take into Carleman matrices) so I need the derivative of its powers. We have just know about the function that: $\int f dx = F$ ${dF \over dx} = f$ ${df \over dx} = a/F$ where a is a constant. I am interested in the following expression: ${d^N \over dx^N} f^M = ?$ A recursive formula is not the best, but really enough. Not to be in PARI/gp is not the best, but enough. (It is important for me to invastigate the infinite Taylor series with argument infinity.) Xorter Unizo « Next Oldest | Next Newest »
