= Riemann–von Mangoldt explicit formula
{c}

For $x>1$ away from a jump of $\psi$,
$$
\psi(x)=x-\sum_\rho\frac{x^\rho}{\rho}
-\log(2\pi)-\frac12\log(1-x^{-2}),
$$
where the sum over <Nontrivial zeros of the Riemann zeta function> is taken symmetrically. A finite-height version has an explicit truncation error controlled by $x/T$ and the distance from $x$ to the nearest prime power.
