Abstract
Many problems in engineering and science can be formulated from the perspective of DEs. The formulation of mathematical models is basically to address real-world problems which have been one of the most important aspects of applied mathematics. It is often the case that these mathematical models are formulated in terms of equations involving functions as well as their derivatives. DEs arise in many areas of science and technology, specifically whenever a deterministic relation involving some continuously varying quantities and their.
