  2. A hanging cable makes a shape called a catenary. Even though it looks like a parabola, it is not a parabola! (for some constant a) Length of curve calculation:

  3. Another example of a catenary is the Gateway Arch in St. Louis, Missouri.

  4. Another example of a catenary is the Gateway Arch in St. Louis, Missouri.

  5. If air resistance is proportional to the square of velocity: y is the distance the object falls in t seconds. A and B are constants.

  6. A third application is the tractrix. (pursuit curve) An example of a real-life situation that can be modeled by a tractrix equation is a semi-truck turning a corner. semi-truck Another example is a boat attached to a rope being pulled by a person walking along the shore. boat

  7. A third application is the tractrix. (pursuit curve) a Both of these situations (and others) can be modeled by: semi-truck a boat

  8. The word tractrix comes from the Latin tractus, which means “to draw, pull or tow”. (Our familiar word “tractor” comes from the same root.) Other examples of a tractrix curve include a heat-seeking missile homing in on a moving airplane, and a dog leaving the front porch and chasing person running on the sidewalk. p
