Someone posted a problem about vectors in this folder a couple of years ago. A member posted a reply, but the member didn't realize that the problem involved vectors. To be fair, the OP didn't provide much context to make that clear.
Anyway, here it is again...
Given that a\(\times\)b = a\(\times\)c and a\(\bullet\)b = a\(\bullet\)c, where a, b, and c are vectors in R\(^{3}\), show that b = c.
The hint given in the original problem is to "cross" both sides of the first equation with a.
