WebbThe prime number theorem is an asymptotic result. It gives an ineffective bound on π(x) as a direct consequence of the definition of the limit: for all ε > 0, there is an S such that for all x > S , However, better bounds on π(x) are known, for instance Pierre Dusart 's. Webbnuance here is that you want to show that if there are to objects satisfying the property that we supposed was unique, then they must be equivalent, which we do here by supposing that they both satisfy the same property (being inverse to a′) but by doing so they end up being equivalent. 7.
