Where standard textbooks rely on basic applications of the AM-GM (Arithmetic Mean-Geometric Mean) or Cauchy-Schwarz inequalities, Volume 2 dives into advanced non-linear structures and symmetric properties.
"Secrets in Inequalities" is generally split into two parts. lays the groundwork, covering five basic inequalities (like AM-GM, Cauchy-Schwarz, and Hölder), along with fundamental techniques such as the derivative method and Abel transformation. It is a comprehensive resource designed to take a motivated learner from the very basics to the level of tackling Olympiad problems.
In essence, Volume 1 is the mandatory prerequisite course, and Volume 2 is the advanced specialization.
Keep Volume 1 handy. If a step in Volume 2 assumes a foundational inequality transition, you will often find its explicit proof in the first volume. Conclusion

into a more manageable state—usually by replacing two variables with their arithmetic or geometric mean—while proving that this transformation strictly decreases or increases the objective function.
Spend at least 30 to 60 minutes trying to solve a model problem using your own tools before looking at Hung’s solution.
Do you need help using these methods?

), you can prove the validity of an inequality without tedious expansions. The book provides specialized rules to handle cases where some coefficients are negative. 3. Geometric and Trigonometric Inequalities
These focus on specialized problems, including applications of Karamata’s inequality, strange inequalities, and improvements to standard inequality techniques.
