User:Jessepfrancis/Ordinary Differential Equations:Cheat Sheet
(This is a book in progress; my knowledge is limited, so feel free to edit/add information as required.)
This book summarizes the learning on solving Ordinary Differential Equations, in much less words as possible. Those who are trying to refresh their learning in ODE might find it useful. If you are looking for detailed explanation of content discussed here, please refer to the Wikibook Ordinary Differential Equations, which the author seems to have abandoned halfway, still contains a great deal of useful information in simple words.
