AI Thread Summary
The discussion centers on the concept of "degree of certainty" in probability, which is referenced in a linked article but lacks clear definition in mathematical literature. Participants express skepticism about its validity, suggesting it may simply be a rephrasing of traditional probability concepts. One contributor highlights a specific formula related to this concept, noting a connection to gambling theory. The formula presented indicates that the degree of certainty approaches approximately 0.63212055. Overall, the theory's soundness remains questionable due to its ambiguous definition and lack of formal recognition in established mathematics.

i found this link and this guy claims there is something called degree of certainty in probability. However, it does not show up in any math book i own. is it valid theory or at least sound?

It looks like he just means "probability."
 
Unfortunately, while his formula involves "degree of certainty" and, in several examples, he gives the "degree of certainty", he never bothers to actually define "degree of certainty"!

A step in the Fundamental Formula of Gambling leads to this relation:

DC = 1 — 1/e

The limit {1 — (1/e)} is approximately 0.63212055...
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
