Also another proofs question,
how the bloody hell do u prove :
a/(b+c) + b/(a+c) + c/(a+b) > 3/2
also does anyone have proofs tips? coz i rlly suck at proofs.
These one's are pretty hard. I've done them before but I seriously can't be bothered to write it.View attachment 30433
so i can do question A by doing LHS- RHS and then doing 2 cases where a>b and a<b so show LHS - RHS >0 ; is there and alternative solution?
and for B and C, I have absolutely no clue.; for B i think you have to add multiple inequalities but i am not sure what inequalities.
