He here gives the proof of THE FUNDAMENTAL THEOREM OF ALGEBRA called d'Alembert's theorem and later corrected by Gauss 1799.The theorem is based on these three assumptions:Every polynomial with real coefficients which is of odd order has a real root. This is a corollary of the intermediate value theorem. Every second order polynomial with complex coefficients has two complex roots. For every polynomial p with real coefficients there exists a field E in which the polynomial may be factored into linear terms.Also with an importent paper by Leonhard Euler "Mémoire sur l'Effet de la Propagation successive de la Lumiere dans l'Apparition tant des Planetes que des Cometes" Memoir on the effect of the successive propogation of light in the appeareance of both comets and planets. Pp. 141-181 and 2 folded engraved plates. - The paper is founded on Euler's theory of light as waves and not as particles. It is from the same year as his fundamental work on light as waves: "Nova Theoria" - Enestroem E 104. </em> unknown
