Homework Statement
Can some explain vector a+b must be great than a-b
Homework Equations
none this is conceptual
The Attempt at a Solution
I believe this is false because the direction can be + or -. can you explain to your thoughts
It is certainly not true in general (not even for scalars). You would need to constrain a and b more to have something that was true.Homework Statement

i think one should try checking the contention that addition of two vectors must be greater than subtraction - as it is true in case of scalars.Can some explain vector a+b must be great than a-b

Is it? Not unless you constrain it to positive scalars...as it is true in case of scalars.
