Web27 Dec 2016 · From my experience, the fundamental theorem of space curves isn't all that fundamental with regard to spaceflight. This is just a movie, and even the most historically accurate of movies get fundamental things wrong. That said, there are a couple of places where the Frenet-Serret frame (or the Serret-Frenet frame) might well have been useful in … Web8 Apr 2024 · Using fractional differential geometry, we define different types of conformable magnetic curves to discuss some geometric features of the motion of the charged particle when its geometry is induced by the conformable fractional derivative. We obtain the non-stretching motions and the inextensibility conditions of the conformable curves to focus …

Webtwo perpendicular. This triple is called the Frenet frame. It is important to note that we can bring this frame onto (e1,e2,e3) by a rotation, where (e1,e2,e3) are the vectors of length 1 pointing in the positive direction of the coordinate axes (this fact is a direct consequence of the right hand rule). Figure1. Thevectors T,N,B inthe figure ... WebFrenet frames. Let γ : I −→ R3be a smooth curve parameterised by arc length. Let T(s) = γ′(s) be the unit tangent vector. As in Section 2, T.T′= 0, so we can write T′= κN, where N is a unit normal to γ and κ(s) = κγ(s) = T′(s) = γ′′(s) ≥ 0. Here κ ≥ 0 — there is no preferred sign. We refer to κ as the curvature of γ.

Webto define the Frenet frame, a condition (a non-degenerate condition) is needed. In general, the parallel curve does not satisfy these conditions. It is well-known that the Bertrand curves of regular curves do not exist under a condition in [19, 21]. In [20], they consider the condition of the Mannheim curves of regular curves. We
