Thanks for your reply. I have not specified it but I want to know the angle between the vectors A and B. For this reason I mentioned the equation: ##|A||B|\cos(\theta) =A \cdot B##.
Even if i read your reply I am still not able to evaluate the angle between them (I want a rigorous solution...
Homework Statement
Ok guys, I'm studying Physics and I started, of course, by learning about vectors.
So I have this problem:
There are two vectors: A (its length is 3 m) and B (its length is 4 m). I have not other informations about them.
I want to know how I can dispose them to get a vector...
