Nov 16, 2022 · Given the vector function, \(\vec r\left( t \right)\), we call \(\vec r'\left( t \right)\) the tangent vector provided it exists and provided \(\vec r'\left( t \right) \ne \vec 0\). The tangent line to \(\vec r\left( t \right)\) at \(P\) is then the line that passes through the point \(P\) and is parallel to the tangent vector, \(\vec r'\left ...
Oct 27, 2024 · Definition: Unit Tangent Vector. Let \(\textbf{r}(t)\) be a differentiable vector valued function and \(\textbf{v}(t)=\textbf{r}'(t)\) be the velocity vector. Then we define the unit tangent vector by as the unit vector in the direction of the velocity vector. \[ \textbf{T}(t) = \dfrac{v(t)}{||v(t)||} \nonumber \]
In mathematics, a tangent vector is a vector that is tangent to a curve or surface at a given point. Tangent vectors are described in the differential geometry of curves in the context of curves in Rn. More generally, tangent vectors are elements of a tangent space of a differentiable manifold.
The velocity \(\vr'(t)\) has dot product zero with \(\vr(t) -h\,\hi-k\,\hj\text{,}\) which is the radius vector from the centre of the circle to the particle. So the velocity is perpendicular to the radius vector, and hence parallel to the tangent vector of the circle at \(\vr(t)\text{.}\)
