Then the Gaussian and mean curvatures of each ruled surface are computed. It is also examined whether the surfaces are developable or minimal. Finally, examples of these surfaces are given and their graphics are drawn.</dc:description><dc:publisher>Maejo University</dc:publisher><dc:date>2023</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/14572</dc:identifier><dc:identifier>1905-7873</dc:identifier><dc:language>en</dc:language><dc:relation>Maejo International Journal of Science and Technology</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/14572</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
