After briefly reviewing the concept of inverse variation, this video explores Boyle?s law, a real world example of an inversely proportional relationship between pressure and volume of a gas. Written and hosted by internationally acclaimed math educator Dr. Monica Neagoy, it goes on to examine similarities and differences among rational functions and numbers. Finally, it takes a look at rational functions graphs and ends with a delightful example merging Euclidean and ana-lytic geometry, thanks to the TI-Nspire technology.
