| Abstract | Fibonacci's forgotten number is the sexagesimal number 1;22,7,42,33,4,40, which he described in 1225 as an approximation to the real root of x[superscript 3] + 2x[superscript 2] + 10x - 20. In decimal notation, this is 1.36880810785...and it is correct to nine decimal digits. Fibonacci did not reveal his method. How did he do it? There is also a curious mistake in his answer: why is it there? We first describe how Leonardo came to know this number. We then introduce several methods that he may have used for approximating roots of polynomials. Finally, we make a guess as to how he really did it. (As Provided). |
