hi!!!
please help me n answer my questions???? what are the effects of rearranging and regrouping series? their difference and some examples. what about convergence after regrouping and rearranging????
Please do NOT "hijack" other peoples threads by asking completely unrelated questions in them! It is extremely rude.
guess, use the "Lagrange Multiplier Method"- the max or min of f(x,y,z) subject to the constraint g(x,y,z)= constant must satisfy for some number .
For this problem, that is . That is, you have , and .
Those fairly easily reduce to y+ z- 4yz= x+ z- 4xz and y+ z- 4yz= x+ y- 4xy. Together with x+ y+ z= 1, you have three equations to solve for x, y, and z.
well , i am not keen on inequalities but i think it is a great attempt !
use
the equality holds when
but it may be wrong because we can find that :
!!
I hope it will be perfectly corrected by some experts .
