ABSTRACT
A general homogeneous equation of this type is d n y d x n + A 1 d n - 1 y d x n - 1 + ⋯ + A n y = 0 . $$ \frac{{d^{n} y}}{{dx^{n} }} + A_{1} \frac{{d^{{n - 1}} y}}{{dx^{{n - 1}} }} + \cdots + A_{n} y = 0 . $$ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315108858/f4dff3a2-1feb-457b-a709-022257f02721/content/math7_1.tif"/>
