The Rabbit Problem (Proof)

The famous Rabbit Problem, known to many of us as a classic mathematical puzzle, was invented by Leonardo Fibonacci and the solution has everything to do with the Fibonacci Series.

Binet's Formula (In Action)

Binet's Formula provides a simple way of finding any Fibonacci number and is easier than the method described in the Introduction--more so for large numbers.

The Successor Formula (In Action)

Another way of finding Fibonacci numbers, The Successor Formula differs from Binet's in that it can be used to find any succeeding Fibonacci number.

Binomial Form (In Action)

Recommended for those already familiar with summation notation, binomial theory, and Pascal's Triangle, this page shows another, more complex way of finding any Fibonacci number.

Fibonacci Spiral (In Action)

A geometric form modeled off the Fibonacci Series. After you've read through the pages in this section, take the "The Series" Quiz.
