Does this pattern have a practical application?
It recently dawned on me (probably someone once realized it too) that if we calculate the sum of a convergent series using the formula: 
, where n is the order of the derivative (in addition to the ordinal number of the term), f (x) is some polynomial, then the root of the resulting polynomial is 1 less than the root of the original polynomial. For example, if 
, then the sum of the series 
. I have a question, where can this regularity be used?
