Hey everyone,
I realize that this is a pretty simple problem but i can't seem to wrap my brain around it. If someone could point me in the right direction i would be thankful.
suppose (vector)C= (vector)A + (vector)B
a) under what circumstances does [(vector)C]= [(vector)A] + [(vector)B]? ( [ ]= absolute value)
b) could [(vector)C]= [(vector)A] - [(Vector)B]? if so how? if not, why not?
ok. for A i was thinking the only way that could be true is if both A and B had the same sign, but I am pretty sure that's wrong.
For B I don't think both C=A+B and [C]=[A]- could be true, but I am not sure why.
If someone could guide me in the right direction i would be grateful. THANKS!
