Finding "verified" solutions for Vladimir Zorich's Mathematical Analysis mathematical analysis zorich solutions verified
Zorich is a Russian mathematician, and in Russia and former Soviet states, his book is a standard textbook. Consequently, there are Russian-language solution books (e.g., Решения задач из курса Зорича) that are professionally verified. If you can read basic mathematical Russian, these are gold. You can find verified and crowdsourced solutions for
Pedagogical Soundness: A verified solution should explain why a particular approach works. It often includes commentary on common pitfalls, alternative proofs, and connections to broader theorems (e.g., Bolzano-Weierstrass, Heine-Borel, etc.). If you can read basic mathematical Russian, these are gold

Problem (Zorich, Section 5.2, modified):
Prove that if $f$ is continuous on $[a,b]$ and $\int_a^b f(x) , dx = 0$, then there exists $c \in [a,b]$ such that $f(c) = 0$.
