- Let f(x) denote some function of x. Let D=d/dx denote the
- operation of differentiation with respect to x.
-
- Question:
- Has anybody ever worked out a formula for D^k f^n, the
- k'th derivative of the n'th power of f(x) with respect to x?
-
- Here `n' is a positive integer, and D^k f is assumed to
- exist for all positive k.
