# About Pi(x) function and price .

Is there a price for getting the Pi(x) function of number theory?..where is the webpage..i think i have discovered a trick to calculate Pi(x) function in number theory..but i can not find someone or some webpage where to send it to.

Just out of curiosity, what is this Pi(x) function?

I think it's the totient function, the number of primes less than or equal to x. http://www.trnicely.net/pi/tabpi.html has some info on it.

Are you trying to sell your solution?

LOL

I think he means

"is there a prize".

isn't Pi(x) top index = n, bottom index = 0 defined to be: an * an-1 * .... * a0 ?

That's the product. It's something different. Pi(x) is a number theory thing. It's also called the Euler's Phi Function, or the totient of x. Pi(x) represents the number of relative primes to a given x.

I would seriously suggest letting someone check your solution before making any claims, as it is certainly not easy to derive mathematical proofs. If it seemed easy, then it may be flawed.
