In differential geometry, what is the Levi - Civita connection? a) A type of differential equation b) A connection between vector fields on a manifold c) A type of curvature tensor d) A type of smooth function

Assume that an object is moving along a parametric curve and the three vector function. T (t), N(t), and B (t) all exist at a particular point on that curve. CIRCLE the ONE statement below that MUST BE TRUE: (a) B. T=1 (b) T x B = N (B is the binormal vector.) v (t) (c) N (t) = |v (t)| (d) N (t) always points in the direction of velocity v (t). (e) a (t) lies in the same plane as T (t) and N (t).
