At 1:46, instead of giving up so soon, just look at the 8 cases of x in [0, π/4], [π/4, π/2], etc., which you looked at anyway. The problem simplifies big time.
Hi i have problem for you Let M (1,2,3.......,n) and A=(a1,a2.a3..........,am ) in M such that m is a natural number #0 And for any b in M there exist ai , aj in group A such that 1
Old IMOs when inequalities used to appear quite often, unfortunately not anymore :-(
Nice video!

indeed @Dennis Desormier ...i was thinking similar. Not sure it would have been simpler than the solution presented though.
Nice
I think Triangle Inequality can make this a lot easier.
You made it unnecessarily lengthy, and complicated, i suppose. Shorter solution shall be uploaded in few hours . Don't mind
@Rick Does Math He's right. This solution is unnecessarily lengthy and complicated.
@Rick Does Math please give sometime. I will upload in my channel, in few hours
@@jose4877 5 step solution comes soon
@Rick Does Math 5 To 6 steps enough.
@Rick Does Math 6 step solution uploaded now in my channel

good
easy to see
very easy question
Level of Russia school exam) enough easy
Just draw the graph with desmos, that'll take care of business
So hard
just like your name 🙃
