Diagonal of 1x1x1 cube = Root-3 !!! Beautiful !! Doesn't that not strike people as mathematically amazing! that the internal diagonal of a 'Cube' (1x1x1) = Root-3 !!! I love the natural relationships with certain numbers, that can easily be proven/shown, and be so simple! 8) GREAT!! Good-ol basic maths can show/prove it all !!!... Then I found out recently, that there is NO KNOWN correct formula, to calculate the Circumference of an 'Ellipse' !! :palm: You don't believe it... then look it up!! Sigh... Just lost faith in Maths again... :box: --- End quote --- Of course there is a correct formula. The relevant observation is found on this page: http://www.numericana.com/answer/ellipse.htm#elliptic "There is no simple exact formula: There are simple formulas but they are not exact, and there are exact formulas but they are not simple."

The one I like is phi, 1.6180339..... In particular phi^2=phi+1 1/phi=phi-1 |

What kind of industries hire theoretical mathematicians? --- End quote --- Q: What does a maths graduate say? A: "You want fries with that?" |
