This is a very hard vector question that even my teacher couldn't anwer!
Attached is the diagram.
The question is as follows:
ABCDEFGH is a regular octagon.
AB = a and AH = b . Express the following vecotrs in terms of a and b:
The answer seems to be more complicated than the question. It is (1+√2)b
This question seems imposible to solve!
But there are many smart people here, so I thought I should give it a try.
Thanks in advance
