Should Pre-Calculus Classes Introduce Hyperbolic Functions?

Click For Summary
SUMMARY

This discussion focuses on the introduction of hyperbolic functions in pre-calculus classes. Participants agree that incorporating hyperbolic functions can enhance students' understanding, especially since these concepts appear in calculus. The discussion highlights two specific resources: a PDF from CIMT and another from Math Articles, which provide accessible introductions to hyperbolic trigonometric functions. The mention of real-world applications, such as the shape of a sagging telephone line, reinforces the relevance of hyperbolic functions in mathematics education.

PREREQUISITES
  • Understanding of basic trigonometric functions
  • Familiarity with calculus concepts
  • Knowledge of function graphs and their properties
  • Ability to interpret mathematical PDFs and resources
NEXT STEPS
  • Explore hyperbolic function identities and their applications
  • Study the relationship between hyperbolic functions and calculus
  • Review the provided PDFs for structured lesson plans on hyperbolic functions
  • Investigate real-world applications of hyperbolic functions in physics and engineering
USEFUL FOR

Mathematics educators, pre-calculus teachers, and students seeking to deepen their understanding of hyperbolic functions and their applications in calculus.

Anyone know of a good unit or introduction online to hyperbolic trig functions which would be good for a pre-calculus level class? Is it worth at least introducing hyperbolic functions to pre-calculus students? I'm ahead of where I'm normally at this time of year in pre-calc, and thought I'd spend a little more time this year on hyperbolic functions, because in calculus, we have about enough time to say, "here are the formulas, here are the derivatives. Pretty similar to the trig derivatives, huh? A sagging telephone line takes the form of a hyperbolic cosine, and they lied to you in algebra when they used the St. Louis Arch as an example of a parabola. It's actually an inverted hyperbolic cosine function."
