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.

@Calvin Lin Sir , recently I posted two questions ..the problem name changed automatically.

Like I named the problem 'Strange' , it changed to 'A geometry problem by Ankit Kumar Jain.

Okay sir .

Sir , can you please suggest some name for the problem I mentioned above so that I can get some idea and I can try to give names that are meaningful from next time.

@Calvin Lin Please help me out!

I was reading the wiki On AM - GM Inequality .In it I found out that there was a proof which said that it requires a bit of combinatorics . In the last bit of the proof , it said

k>mg>0mg(0,k)k > m_g > 0 \Rightarrow m_g \in {(0 , k)}

kma>0ma(0,k]k \geq m_a > 0 \Rightarrow m_a \in {(0 , k]}.

From these how does it follow that mamgm_a \geq m_g ?

I don't know what k,mak, m_a and mgm_g represents. So I can't help you with that...

@Pi Han Goh Sir mam_a is the arithmetic mean and mgm_g is geometric mean and kk is some constant.

@Pi Han Goh AM-GM .In the proof that says 'It requires a bit of combinatorics' , that one.
