Is there some methods to solve equations with MIN operation?
Hi everyone, I have to solve a set of equations with MIN operation. MIN operation: For an equation MIN{x1, x2, ..., xn} = a, "a" is the minimal value among x1 to xn. A set of equations with MIN operation is like: MIN{x1, x2} = b MIN{x3, x4} = c MIN{x2+x3, x5} = d ...... Is it possible to solve or pa... 4 Aug 2010 03:51

"Given an even number N, if we subtract from it the odd primes 3,5, 7...p(n) then the number n of primes needed for obtaining the first prime difference will be ever less than 0.72*(Ln N)^2" Example: Be N = 3807404, its necessary to subtract to the 132th prime , to obtain a prime difference. 3807404 - 751 = 3... 30 Jul 2010 19:40

cube = inside sphere + hyperboloid Re: strip-geometry-building as reversal of Calculus #4.29 & #244 Correcting Math & Atom Totality
I do not remember where the word "calculus" comes from, but if I were to rename it today it should be called the "strip decomposition process" and it would include the integration and differentiation. And the reverse would be the "strip building process" and it maybe given the name "recalculus" for it is the rever... 28 Jul 2010 08:33
