The line element in mathematics can most generally be thought of as the square of the change in a position vector in an affine space equated to the square of the change of the arc length. An easy way of visualizing this relationship is by parametrizing the given curve by Frenet's formulas. As such, the line element is then naturally a function of the metric, and can be related to the curvature tensor.
