Hello.
The topic:  reciprocal of a vector
It's not specifically mentioned, but it can be used in solving pther problem in vectors.
That means no direct question on this topic will be asked, but it maybe required(may alternative exist) in solving a problem.
It's a small concept, better to clear the concept.
Thank you.
