Also, we examine the timelike helices of R-2(4), taking into account their curvatures. In addition, we study timelike slant helices, timelike B-1-slant helices, timelike B-2-slant helices in four dimensional semi-Euclidean space, R-2(4). And then we obtain an approximate solution for the timelike B-1 slant helix with Taylor matrix collocation method.eninfo:eu-repo/semantics/closedAccessSemi-Euclidean spacetimelike curvestimelike slant helixtimelike helixTaylor matrix collocation methodArticle44331032410.5831/HMJ.2022.44.3.310WOS:000890292100001N/A
