Homework Statement



If A-B-C (vectors) and A^2+ B^2+ c^2 where X is the magnitude of X(vector) for X-A,B,C, then the vectors A and B are perpendicular to each other. (True or false?)

The Attempt at a Solution



Honestly, I never post anything unless I have it at least halfway solved. But I'm completely confused by this question. Can anyone help me?

i didnt get the question...kindly phrase it again!
 
Ahhh...so it's not just me? Maybe there was a typo in this sheet, but that's how the question was phrased. I suppose they mean X is the magnitude of X(vector) for X-A, X-B, and X-C. The first expression (A-B-C) is in vector notation, but the second one (A^2 + B^2 + C^2) is not. I'm not sure if that clarifies anything. Maybe it's just a poorly written question?

The question does not make sense to me either. However, perhaps this is deliberate and the answer is false? :smile:
