The Unit Tangent Vector. The derivative of a vector valued function gives a new vector valued function that is tangent to the defined curve. The analogue to the slope of the tangent line is the direction of the tangent line.

The radius of curvature of a curve at a point M(x,y) is called the inverse of the curvature K of the curve at this point: R=1K. Hence for plane curves given by the explicit equation y=f(x), the radius of curvature at a point M(x,y) is given by the following expression: R=[1+(y′(x))2]32|y′′(x)|.

Velocity is the instantaneous rate of change of displacement. So at any instant in circular motion the displacement of the body takes place along the tangent to the circle. So which indicates the velocity to be tangential.

From my experience with physics, velocity is a tangent, while “speed” is a number, a scalar. Speed measures how fast an object is moving, but velocity also says in which direction it is moving. So, dr/dt as a vector will be the velocity, ‖dr/dt‖, i.e. its norm, will be the speed.
