Vector Projections

[ccruje]

I am stuck at this homework question :(

Given that a and b are vectors, when is vector projection of a on b = vector projection of b on a?

As i work it out, I am left with vector a divided by length of a squared = vector b divided by length of b squared or:
a/|a|^2=b/|b|^2
Does this simply imply that vector projections equal if, and only if, a and be were the same vectors.

I really appreciate the help! Thanks!

I answered in the other thread you made ;)

Next time, if you can refrain from making multiple threads, that would be awesome. It can be frustrating trying to coordinate answers from multiple threads (especially if two people give you different answers!).
