ABSTRACT
In the solution to differential equationst either in abstract terms or in specific instancest one frequently arrives at an integral of the general form I ( x ) = ∫ L q ( x ) L 2 ( x ) F ( x t ξ ) d ξ . $$ I(x) = \mathop \smallint \limits_{{L_{q} (x)}}^{{L_{2} (x)}} F(x_{t} \xi )d\xi . $$ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315108858/f4dff3a2-1feb-457b-a709-022257f02721/content/math1_1.tif"/>
