Calculate the magnitude of a when a = (2, 3, 2). Find (1/a)xa. Is it a unit vector.
I calculated the a = sqrt17. I don't know how to determine if it's a unit vector or not?

drwls,
It is not a unit vector unless its magnitude is 1. To make it a unit vector, all three components would have to be divided by sqrt17.
