That reminds me ... wasn't Stephen Wolfram on math-fun for a while way back in the day? Is this a false memory? On Sun, Dec 7, 2014 at 7:23 PM, Dan Asimov <dasimov@earthlink.net> wrote:
Assume u(x) and v(x) are arbitrary infinitely differentiable functions R -> R.
Suppose I want to find the 7th derivative f^(7)(x) of
f(x) := (u(x)^2 + 1) / (v(x)^2 + 1)
Is there a straightforward (or otherwise) way to do this in Mma???
Even better, can it give a general formula for the nth derivative in terms of n ???
(The online Mma documentation is pretty good -- much better than what you get with a ?? command while running the program -- but it doesn't make finding the answer to such questions easy.)
Thanks,
