Hi MIF;

Looks good. Thanks for the page.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Hi;

For someone whose business acumen consists of only knowing when they overcharged me it is quite intimidating. But I think I got it!

Hi MathsIsFun

Been away, so only just seen this.  Looks good and it is clear.

Just one suggestion.

About 3/4 down, where you are using a calculator, you say

1.10 to power 6 is better than 1.10 x 1.10 x 1.10 x 1.10 x 1.10 x 1.10

Could you say is quicker to calculate ?

Quicker is better, so better will become quicker.

Interesting paper. Good use of the guess and try idea.
