Now I know there is a formula for it but our teacher showed us an easier way than the formula but I forgot how it works. I was hoping someone had way to walk me through it, please. Thanks.

This work explores a second-order differential equation with neutral terms of a sublinear and superlinear form, which can be expressed as follows: $$\begin{aligned} \left( \hslash (\textrm{s})\left[ ...

Differential equations have become essential tools for modeling real-life problems in various fields, including biology, mathematical finance, and engineering (see 1 and 2). Many researchers have ...
