How did Ramanujan prove the Bertrand's postulate? Part 1

This video marks the first step in our journey to understand one of the key results used by Ramanujan in his proof of the Bertrand Postulate. Here, we focus on proving the first lemma, a foundational result that Ramanujan employed to build his elegant and ingenious argument. By carefully working through this lemma, we set the stage for uncovering the deeper insights and techniques that underpin his proof of this important number-theoretic result.

Very good man! Can you do more Ramanujan proofs please?
