Hello...
BIG question (big for me, at least): Is there a general formula for the n-th derivative of
Basically I have a function exactly like that and I need to extract the n-th derivative.
THANKS in advance
There's a formula for taking the nth derivative of any function of the form y = f(x) g(x) called Leibniz's Rule.
If then , where is some polynomial in u and its derivatives. If you differentiate one more time then you get . So . If you apply this recursive formula to find the first few derivatives then you get

That should be enough to convince you that there is not going to be any simple formula for the n-th derivative.
