A tangent unit vector is useful for determining the direction of motion of a curve at a specific point. It can also be used to calculate the curvature of a curve at that point. Can a tangent unit vector be negative? Yes, a tangent unit vector can have a negative direction. This indicat...
Tracking a homotopy curve involves finding the unit tangent vector at different points along the zero curve, which amounts to calculating the kernel of the n × (n + 1) Jacobian matrix Dρa(λ, x). While computing the tangent vector is just one part of the curve tracking algorithm, it...

In mathematics, the tangent vector of a planar curve is the vector tangent to this curve. For the parametric curve related to Eq. (2.5), its unit tangent vector t can be expressed as (2.15)t=P′t‖P′t‖=1x′t2+y′t2x′ty′tT The normal vector measures the variation of the tangen...
In vector calculus, slope is used to find the vector parallel to a tangent line to the curve. Slope of a curve {eq}y=f(x) {/eq} is {eq}m=f'(x) {/eq}. Now using the slope, parallel vector is expressed by the formula {eq}\mathbf i+m \mathbf j {/eq} an...
Normal Curvature Let t = r u du + r v dv is a tangent vector of a surface M ∈ R3 , then the planar curve C at intersection between M and normal section plane has a curvature Kn (t ) at point r (u, v) which is called the normal curvature of M in the direction t. Given ...
