I need help w/ "Given a=i+2j-2k, find y, z so b=yj+zk is perp. unit vector."
Hi everyone!
I have an admission exam coming up and they gave us a sample exam paper with no answer.
Below is the question that I'm trying to figure out.
Q: Given the vector a=i+2j-2k, find a possible set of value for y and z such that b=yj+zk is a unit vector that is perpendicular to a.
This is what i get so far,
since a is perpendicular to b, their dot product would be 0, therefore y and z = 0.
Would really appreciate your help! Thank you!
