FUR'E METHOD OF SOLVING BORDER AND INTERFERENCE PROBLEMS FOR WAVE EQUATIONS

Abstract

One of the most widely used methods in the solution of boundary or mixed problems in the theory of differential equations with special derivatives is the method of separation of these variables or the Fourier method. In this paper, this method is considered in the example of boundary value problem 1, which is applied to the equation of free oscillation of a network with tightly fixed ends.
