Some examples are solved to demonstrate the accuracy of DJM. A comparison study between DJM, the variational iteration method (VIM), and the exact solution are presented. The comparison of the present symmetrical results with the existing literature is satisfactory.<\/jats:p>","DOI":"10.3390\/sym14010057","type":"journal-article","created":{"date-parts":[[2022,1,9]],"date-time":"2022-01-09T23:35:09Z","timestamp":1641771309000},"page":"57","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["New Solution of the Sine-Gordon Equation by the Daftardar-Gejji and Jafari Method"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2393-4418","authenticated-orcid":false,"given":"Belal","family":"Batiha","sequence":"first","affiliation":[{"name":"Department of Mathematics, Faculty of Science and Information Technology, Jadara University, Irbid 21110, Jordan"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"277","DOI":"10.1016\/0375-9601(88)90027-8","article-title":"Exact and explicit solitary wave solutions for the generalized Fisher equation","volume":"131","author":"Wang","year":"1988","journal-title":"J.
