Equality of vectors

If two vectors look exactly alike with regard to length and direction, then they are exactly the same vector. Positioning of the vectors does not matter. In the picture here, tex2html_wrap_inline583 and tex2html_wrap_inline585 have a common length and direction, so they are equal and we can write tex2html_wrap_inline587 .
