Since there exists a positive constant co such that ( sin 0 2 colsin ( 0/2 ) for 0 5 10 $ / 2 , formula ( 30 ) follows at once . Using ( 27 ) , ( 30 ) , and ( 31 ) , we see that there exists a finite constant M ' independent of ε such ...

This shows that there exists a finite absolute constant c ' such that I ( Q ) ] = c ' ( 1 + 1 & 1 ) -n + 1 . Using this inequality and using ( 37 ) , we see that there exists a finite constant M " independent of ε such that av av 22V ...
