nope :)

sorry i rephrased the question a bit wrong because i was in a hurry

i really meant it to be one of those "i dont understand what i did wrong" type questions

essentially what i was trying to do was to use the triangular inequality in the reverse, to cram the two absolute brackets into one

is anyone able to correct what i have done? or provide an alternative? - March 31st 2010, 03:44 AMHallsofIvy
Before we can tell you what you did wrong, we will have to know what you did and what you were trying to do! So far, all you have asked us to do was to verify a certain inequality which skeeter has already told you is wrong.
