RMO INMO prep question?

Which inequalities are important for RMO and INMO, apart from AM GM and cauchy schwarz?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

See First for RMO, be precise with Rearrangement inequality, AM-GM and cauchy scwartz. The Trick lies within Seeing the problem and analyzing it various forms. Well All the Best for your exam.

I don't think that rearrangement is required for RMO, AM-GM and CS are enough to handle RMO,if you use them smartly.The main thing in inequality problems is to shape the inequality into a obvious AM-GM or CS form.And Angel's form of CS is also very very important.I am also giving RMO so all the best.!!!
