Tangent Unit Vector Definition

A tangent unit vector is a vector that points in the direction of the tangent line to a curve at a given point. It is a unit vector, meaning that its magnitude is 1. Tangent unit vectors are used in a variety of applications, including:

Calculating the velocity and acceleration of a particle moving along a curve
Determining the direction of the force acting on an object moving along a curve
Finding the equation of the tangent line to a curve

The mathematical formula for calculating a tangent unit vector is:

$$\mathbfT = \frac\mathbfr'(t)\Vert \mathbfr'(t) \Vert$$

where:

$\mathbfr(t)$ is the position vector of the particle at time $t$
$\mathbfr'(t)$ is the velocity vector of the particle at time $t$
$\Vert \mathbfr'(t) \Vert$ is the magnitude of the velocity vector
