Normal vectors of a Curve Definition: at a point where κ≠0, the principal unit normal vector for a smooth curve in the plane is N=1κdTds. 关于,N 我们知道以下几点: 1、 ∵r⋅drdt=0∴N⋅T=1κ(dTds⋅T)=0, 即和N和T 相互垂直。 2、 1κ系数使得 N 也成为单位向量。 3、 ...
Question: Find the principal unit normal vector to the curve at the specified value of the parameter. {eq}r(t)= 6 cos (t)i + 6 sin (t) j + k, t = \frac{3 \pi}{4} {/eq} Unit Tangent, Normal and Binormal Vecto...
i always keep forgetting dr is the tangent to the plane of surface. thanks ehild. could you help with what a unit normal vector is ?? is it the direction of the gradient vector? if so, how do you calculate it given the gradient and a point on the surface ? See the original post...
Truly Bizarre - The unit tangent and unit normal vectors aren't orthogonal OK, this looks like a differential geometry problem, which it is, but at the end of the day I am trying to figure out why the unit normal and unit tangent vectors to a curve aren't orthogonal, so even if you...

Given the curve r(t)=(t^2+3t, t^2-1, 3t+1) find (i) the unit normal, N(t)=T'(t) / |T'(t)| and (ii) the binormal vector, B(t)= T(t) times N(t) at the point P(4,0,4). Find the unit tangent vector and the principal unit...
