Homework Equations
The Attempt at a Solution
Okay so I'm pretty stuck to say the least..any help would be great..Here are some thoughts:
1)doesnt this just mean we sum that components of a and c and b can take any value? I'm confused..does this mean the result is a vector.?
2)so we sum a and d and b and c..but how do i simplify this?
3)ok so this one i think i know...isn't it just ajaj so sum the components of a? a.a?
4)doesnt this just equal dij?
5) Not sure
6) Again,not sure :(
thanks
