Web0. You cannot "invert" a power series (P.S.) by inverting term by term. If you want to find the inverse of a function of which a powerseries representation is established, you got to kind of start all over. For example, there is a P.S. for sinx. But reciprocating these polynomial terms does not get the P.S. for the cosecant function.
