ABSTRACT
The Sturm-Liouville system comprises a differential equation of the form d dx [ p ( x ) dy dx ] + [ λ r ( x ) - q ( x ) ] y = 0 , $$ \frac{d}{{dx}}[p(x)\frac{{dy}}{{dx}}] + [\lambda r(x) - q(x)]y = 0, $$ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315108858/f4dff3a2-1feb-457b-a709-022257f02721/content/math11_1.tif"/>
