Richard Askey 

May 2005, Volume 98, Issue 9, Page 610

Abstract:

Fibonacci and Lucas numbers. Beautiful connections are established between seemingly unrelated mathematical territories, Fibonacci-Lucas numbers and hyperbolic trigonometric functions. Delving Deeper is for teachers to pose and solve novel math problems, expand on mathematical connections, or offer new insights into familiar math concepts. Delving Deeper focuses on mathematics content appealing to secondary school teachers. It provides a forum that allows classroom teachers to share their mathematics from their work with students, their classroom investigations and products, and their other experiences. Delving Deeper is a regular department of Mathematics Teacher.
