We obtain new solutions with complex, hyperbolic and trigonometric function structures. All the obtained solutions in this paper verified their corresponding equations. We also plot the three- and two-dimensional graphics of all the obtained solutions in this paper by using the same program in Wolfram Mathematica 9. We finally submit a comprehensive conclusion.</dc:description><dc:publisher>Scientific Publishers</dc:publisher><dc:date>2017</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/munzur/3896</dc:identifier><dc:identifier>https://doi.org/10.1007/s12648-017-1033-z</dc:identifier><dc:identifier>0973-1458</dc:identifier><dc:language>en</dc:language><dc:relation>Indian Journal of Physics</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/3896</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
