Excerpt from Order of Magnitude Reasoning in Qualitative Differential Equations
The paper is organized as follows: Section 2 presents fundamental definitions and rules that govern the behavior of a solution to a set of qualitative differential equations. The basis of the definitions and the justifications of the rules lie in the theory of non-standard analysis with infinitesimals. Section 3 shows how these rules may be applied in the heavy block on the spring example and other examples. Section 4 presents an algorithm for constructing an envisionment graph from a set of qualitative differential equations. Section 5 discusses the chepachet program, which implements this algorithm. Section 6 makes suggestions for further work. We assume that the reader is familiar with standard theories of envisionment.

Paperback. Zustand: New. Print on Demand. This book presents qualitative differential equations, which combines order-of-magnitude reasoning with envisionment of mathematical equations. The theory presented in this book can be applied to dynamical systems containing parameters of various magnitudes. The author proposes two key innovations. Firstly, each state of the system is given a duration and the net change to each parameter during the state. Secondly, the author introduces a set of rules governing the behavior of functions over orders of magnitude. These innovations extend the reader's ability to analyze the dynamic behavior of systems, enabling inferences about systems with quantities of widely varying magnitudes.
