چکیده
|
We present the best possible parameters 1,1 r and 2,2 1/2,1 such that double inequalities 1c(a,b)+1-1a(a,b)0 with a≠b,where a(a,b)=(a+b)/2,c(a,b)=a3+b3/a2+b2 and t(a,b)=2∫0π/2a2cos2θ+b2sin2θdθ/π are the arithmetic,second contraharmonic,and toader means of a and b,respectively. © 2015 wei-mao qian et al.
