ABSTRACT
An nth-order homogeneous linear equation with constant coefficients has the general form y x ( n ) + a n - 1 y x ( n - 1 ) + ⋯ + a 1 y x ′ + a 0 y = 0 . . $$ y_{x}^{{(n)}} + a_{{n - 1}} y_{x}^{{(n - 1)}} + \cdots + a_{1} y_{x}^{'} + a_{0} y = 0. . $$ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315117638/585bf32b-5ab3-4664-8be7-28e9abefef4b/content/math4_1.tif"/>
