ABSTRACT
Frequently it is possible to obtain a solution to a differential equation in the form of a power series: y = ∑ k = 0 ∞ A k ( x - x 0 ) k $$ y = \mathop \sum \limits_{{k = 0}}^{\infty } A_{k} (x - x_{0} )^{k} $$ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315108858/f4dff3a2-1feb-457b-a709-022257f02721/content/math8_1.tif"/>
