As the above title suggests, the method is based on making “good guesses” regar din these particular solutions. And, as always, “good guessing” is usually aided by a thoroug h nderstanding of the problem (the ‘education’), and usually works best if the problem is s imple enough. Fortunately, you have had the necessary education, and a great many nonhomogeneou s differential equations of interest are sufficiently simple. As usual, we will start with second-order equations, and the n observe that everything developed also applies, with little modification, to similar nonh mogeneous differential equations of any order.","PeriodicalId":198170,"journal":{"name":"Ordinary Differential Equations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114546168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
