A systems technician is calibrating a tracking system that maps an object's position along a curve. This curve is defined by the property that the difference in distance between the object and two fixed reference points remains constant at all times. In this geometric model, what is the technical term for these two fixed reference points?

An acoustic engineer is mapping a sound interference pattern that forms a hyperbolic curve. The definition of this curve relies on two fixed points, where the difference in distance from any point on the curve to these two points is always constant. Each of these fixed reference points is mathematically referred to as a ____ of the hyperbola.

An aerospace engineer is designing a hyperbolic reflector for a satellite tracking system. By mathematical definition, the two fixed points used to determine the geometry of this hyperbolic curve are called the foci, and for every point on the curve, the difference of the distances to these two points remains constant.

Geometric Principles of Hyperbolic Tracking

A network engineer is calibrating a precision timing system used for hyperbolic trilateration. The system identifies an object's location by modeling a path based on the time-delay between two fixed sensors. Match each geometric term with its specific role in defining this tracking model.
