These vectors are giving me some real trouble...i'm fine with the in physics, but the math theory behind them is my weakness...(adsbygoogle = window.adsbygoogle || []).push({});

Ok, so we have that u.v=u.w where those are dot products of vectors. The question asks whether or not it makes sense to equate that to meaning that v=w.

Now, at first glance I would say yes. Since u never changes, for the dot product to be the same of the 2 expressions v and w would have to be the same vectors. But i have a strong feeling that i'm wrong...seems like one of those questions designed to make you second-guess yourself.

Any pointers on how to work this one out would be appreciated
