Bir eğrinin asli normaller göstergesinin doğrultu eğrileri

Öz

Helisler ve slant helisler, doğada ve bilimde sıklıkla karşılaştığımız, bilgisayar destekli geometrik tasarımdan fraktal geometriye, kinematikten DNA çiftlerine, geniş bir kullanım alanına sahip olan eğrilerdir. Bu çalışmada, 3-boyutlu Öklid uzayında bir eğrinin asli normaller göstergesinin doğrultu eğrileri tanımlanmış ve bu eğrilerin Frenet vektörleri ve eğrilikleri arasındaki ilişkiler bulunmuştur. Bu doğrultu eğrileri kullanılarak, küresel eğrilerden helis ve slant helisler oluşturmak için kullanışlı yöntemler elde edilmiştir. Son olarak, konu ile ilgili bir örnek verilmiştir.

Direction curves of principal normal indicatrix of a curve

Öz

Helices and slant helices are curves which are often encountered in nature and science and have a wide range of uses including computer aided geometric design, fractal geometry, kinematics, and DNA double. In this paper, direction curves of principal normal indicatrix of a curve in Euclidean 3-space are defined and some relationships between Frenet vectors and curvatures of these curves are found. By using these direction curves, some useful methods to construct helices and slant helices from spherical curves are obtained. Finally, a related example is given.
