The Riemann zeta function ζ(s) is initially defined for complex numbers s with real part greater than 1 by the absolutely convergent series ζ(s)=∑n=1∞n−s, and admits a unique meromorphic continuation to the entire complex plane with a single simple pole at s=1. The trivial zeros of ζ(s) are the negative even integers −2,−4,−6,…. Prove that every zero s of ζ(s) that is neither equal to 1 nor a trivial zero satisfies Re(s)=21.
