I was further looking into the Cauchy schwarz inequality and i got to a statement as follows:(adsbygoogle = window.adsbygoogle || []).push({});

A·B ≤ |A·B|

However, when I tried to prove this using numbers on paper, I wasn't sure if the absolute value bars distribute among each term, which would lead to |A|·|B|, or if the final product is then absolute.

I was wondering how you would interpret the above statement (assuming all capital letters represent vectors

These are the components I assumed.

A= {1,2} B= {-2,3} c= -2

Also how would the following below be interpreted?

|cA·B|

Thank you.
