Summary
Assume that {T, N, B} be the Frenet frame field along γ. The Frenet frame satisfies the following Frenet–Serret equations:. ( [14]) Let γ : I −→ Sol[3] be a unit speed non-geodesic general helix. The parametric equations of γ are sin Pe− cos Ps−C3 x (s) =. Z (s) = cos Ps + C3, where C1, C2, C3, C4, C5 are constants of integration. Parallel Surfaces to Normal Ruled Surfaces of General Helices in Sol[3]. The purpose of this section is to study parallel surfaces to normal ruled surfaces of general helices in Sol[3]. Let γ : I −→ Sol[3] is a unit speed non-geodesic general helix in Sol[3]. The equation of normal ruled surface of γ is
