The Golden Ratio
The Golden Ratio (approximately 1.618) is a number with some very interesting properties that have mystified and fascinated mathematicians for centuries! On these pages I will show you just a few of the interesting
things that you can do with this number. We'll start with a brief introduction to the number, and then move on to the "fun stuff".
Just a little bit of historical information about The Golden Ratio, as we get started.
This interesting number shows up in nature, in some surprising ways.
A special angle that we don't often mention in Trigonometry classes, 36° has some interesting trig values!
The Golden Ratio can be written as a continued fraction; click here for the fraction and the proof.
The Golden Ratio can also be written as a continued radical; click here for the radical and proof.
The Golden Ratio is intimately connected with the Fibonacci Sequence.
What if a Fibonacci Sequence is also a geometric sequence? I bet you can guess the answer to that...
Just for fun, here, let's see what happens when we mix math and numerology!
