Generate explicit formula for mth derivative
显示 更早的评论
I'd like to generate an explicit formula for the mth derivative of x^n, for example:
diff( x^n, x $ m )
The result in MuPad is d^m/dx^m( x^n ), but I want MuPad to write the explicit formula (which I believe is n!/(n-m)! x^(n-m))

The older Maple symbolic engine can do this, yielding pochhammer(n-m+1, m)*x^(n-m)
I do not have access to MuPAD to test with.
