Video Transcript: Algebra Applications: Rational Functions Video Transcript: Algebra Applications: Rational Functions Video Transcript: Algebra Applications: Rational Functions

This is the transcript for the video of same title. Video contents: In this episode of Algebra Applications, students explore various scenarios that can be explained through the use of rational functions. Such disparate phenomena as submarines, photography, and the appearance of certain organisms can be explained through rational function models.

Video Transcript: Algebra Applications: Rational Functions, Segment 1: Submarines Video Transcript: Algebra Applications: Rational Functions, Segment 1: Submarines Video Transcript: Algebra Applications: Rational Functions, Segment 1: Submarines

This is the transcript for the video of same title. Video contents: In spite of their massive size, submarines are precision instruments. A submarine must withstand large amounts of water pressure; otherwise, a serious breach can occur. Rational functions are used to study the relationship between water pressure and volume. Students graph rational functions to study the forces at work with a submarine.

Video Transcript: Algebra Applications: Rational Functions, Segment 2: Biology Video Transcript: Algebra Applications: Rational Functions, Segment 2: Biology Video Transcript: Algebra Applications: Rational Functions, Segment 2: Biology

This is the transcript for the video of same title. Video contents: All living things take up a certain amount of space, and therefore have volume. They also have a certain amount of surface area. The ratio of surface area to volume, which is a rational function, reveals important information about the organism. Students look at different graphs of these functions for different organisms.

Video Transcript: Algebra Nspirations: Rational Functions and Expressions Video Transcript: Algebra Nspirations: Rational Functions and Expressions Video Transcript: Algebra Nspirations: Rational Functions and Expressions

This is the transcript for the video of same title. Video contents: 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 analytic geometry, thanks to the TI-Nspire technology. Concepts explored: functions, rational expressions, rational functions, asymptotes
