My confusion is about this power series.

If derivative of a function (f(x)) is another function(g(x)) then, this holds for the series terms of the functions.

My question is If one knows this derivation relation Just two equal labelled series terms of two other functions. And one term is exactly the differential of the other Then can we generelize this relation for the "big " functions?

Thanx
