In this document, we will show that:
. [1 − ඨ1 −
] − 7
might be a better approximation for the prime-counting function than ߨሺݔሻ =

The following document originated during our study of primes and the reading
about the Riemann hypothesis [2,3].
We were baffled by the fact that the young Riemann had found such a complex
formula as a proposition for to the prime-counting function.
We were curious to find a better formula.
Methods & Techniques
We used Microsoft Excel to do our calculations.
