BobbyJoeCool Posted September 18, 2005 Share Posted September 18, 2005 I have a vague recolection from Pre-Calculus of learning about unit vectors... Vector "i" and "j"... one of which goes from (0,0) to (0,1), the other (0,0) to (1,0). Does any this ring a bell to anyone? and if so, can you tell me which one is which? I can't seem to find it. I think "i" is (0,0) -> (0,1), and "j" is (0,0) -> (1,0). And, is there one of these for the thrid dimention? (eg, from (0,0,0) -> (0,0,1)) Link to comment Share on other sites More sharing options...
Dave Posted September 18, 2005 Share Posted September 18, 2005 Wrong way around [imath]\vec{i} = (1,0,0), \vec{j} = (0,1,0), \vec{k} = (0,0,1)[/imath]. k is the symbol denoted for the z-axis unit vector. Link to comment Share on other sites More sharing options...
