Öz

In this study, the representation formulas of non-null curves are primarily expressed in four dimensional semi-Euclidean space E₂⁴ and the non-null normal curves in E₂⁴ are examined and some certain results of describing the nun-null normal curve are presented in detail in E_2^4. In addition, some mathematical conditions are expressed for a curve given in four dimensional semi-Euclidean space E₂⁴ to be a nun-null normal curve as theorems.
