Hello! I'm looking for help to solve part b of this problem (the answer to part a is " a - 4b ").
I know that because it is a square, the diagonals are equal in magnitude and perpendicular, meaning the dot product would be equal to zero, but was unable to obtain a version with just |a| and |b| and not |ab|, or something that would otherwise allow me to derive |a| = 2|b|2
This is my first post so sorry if I put it under the wrong category. Please give a senior high-school level answer otherwise my brain might explode. Thanks!
