Cauchy/ Triangle Inequality
I was wonder what conditions a and b have to be for each inequality in order to satifsy the equality?

Cauchy's inequality is just the trivial a . b <= ab Oo
Triangle inequality a+b = a +b 
Re: Cauchy/ Triangle Inequality
What do you think happens when a,b are both postive or both negative ?

Re: Cauchy/ Triangle Inequality
Just go over the proof, and you'll probably see it.
