Solution of a Boundary Value Problem Using the Differential Transformation Method

Consider the following two boundary value problems, the first linear and the second nonlinear: (1) with and , and (2) with and .
This Demonstration applies the differential transformation method (DTM) to solve these two problems. You can vary the parameter as well as the order of the Taylor series expansion, . Excellent agreement is obtained between the result of the DTM (blue dashed curve) and its shooting technique counterpart (red curve) for large values of .
