WebWhen I sketch the graph for a general second degree polynomial y = a x 2 + b x + c it is easy to "see" its roots by looking at the points where y = 0. This is true also for any n -degree polynomial. But that's assuming the roots are real. For y = x 2 + 10, the solutions are complex and I (of course) won't find the zeros when y = 0. My question is: WebThe 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. northeastern exterminating
