Detailed Description

This defines a parabolic arc, or subset of an arc, similar to the path of a projectile or falling object.

It is finite, having a specific beginning and end, but it is infinitely thin.

Think of it as a wire bending from point t1 to point t2 along the path of a pre-defined parabola.
