If vector A=10i+49j, and vector B=vector A/2, then does vector B=1/2(10i+49j)?

Re: Vectors

Yep. So how would you write out vector B then?

Re: Vectors

would it be 5i+24.5j?

Re: Vectors

Yes. The main point here is that when it is written that e.g. B = A/2, it means that each component of the vector B is half the value of the corresponding component of A. The same thing goes for multiplication by a number, e.g. C = 2*A. In that case you would have C = 20i + 98j.
