Abstract
Attention is focused on the adequateness of "The straight Line" model, which is first constructed by strickland and Angelopoulos in solving a non-homogeneous boundary value problem with the method of finite Hankel transform. Numerical Treatment and Exact Analytical solution are analyzed to be used as the standard of comparison. Numerical results are obtained with the aid of computing mechine. The result leads to a better assumption-hypobolic function than the straight line.
