Yet it has cost years of work to solve the problem in its whole universality (using the term in the mathematical sense, viz., for that which is sufficient for all cases), and finally to exhibit it in the analytical form, as the reader finds it here.
Era berean, urte luzetako lanak kostatu da problema hori bere orokortasun guztian soluzionatzea (hitz hori ulertu behar baita matematikariek ulertzen duten bezala, alegia, kasu guztietarako behar hainbat balio izateko moduan), eta hori, azkenik, modu analitikoan aurkeztu ahal izatea, irakurleak hemen aurkituko duen moduan.
