So I'm having this problem (linear algebra).
Given that vector a is defined as OA, and b as OB. I need to express other ones in function of those ones.
I currently found that BA is b-a and DE is -a+b and also that OD is -a and DA is 2a. All using the definition of vectors. (I'm studying using Fraleigh's linear algebra.
But, the problem arise when trying to express BC cause I don't realize how. I now that since this is a regular hexagon the norm'll be the same as the BA and actually the other sides but can't express in terms of a and b.
Any help? Thanks.
