If the coefficient alone were all that is necessary, then, once this is determined, all that concerns the theory would be taken care of in less than half an hour, as we said; the omission of the further terms of the series would present no difficulty far from it, for such terms, as terms of the series (their determination as second, third, etc., function is already absolved with the determination of the first), would not come into question at all since they are of no relevance.
