%T The Generalization of the cosinus theorem and analytical calculation of multi-beam interference with an arbitrary phase distribution
%K
%X An important task of signal transmission systems is to calculate the result of the addition of oscillations analytically solved for two signals. In this paper, we obtained an analytical solution to the problem of calculating the result of adding an arbitrary number of unidirectional oscillations or signals. A formula is obtained for generalizing the cosine theorem for a triangle to the case of polygons of various configurations. Examples of calculating the parameters of polygons of various shapes are given.
