Vectors II Return of the Problem

[ppacc]

I've corrected the question, plus there were issues Yesterday with the LaTeX graphics
Please Help! I just don’t get it and I’ve been studying for days.

Question :
Knowing that Vectors C = (4i+1j-3k) meters and D=(2i-3j-5k) meters
Determine:
a. S=C-D
b. │S│
c. The Unit vector in the direction of S

My Prof has given us a test one week after the first class and I just don’t get these study questions. I can add and multiply vectots but this stuff I just don’t get and there is no one to help.

If anyone out there can help you’ll really be appreciated

Well, I think all the answers have been given in the posts, yesterday...

I wrote x,y,z in stead of i,j,k, but that shouldn't be a problem
