help the newbi plz I had a question about vectors and scalars. Can you explain it to me, and I also had a problem with this question. here is the question: Three vectors A,B, and c having magnitude of 50 units like in the x-y plane and makes angle of 30, 195,315 with positve x axis. find graphically and direction of the vectors. A) a+b+c b) A-b+c Can you guys also expalin the multipicaiton of vectors also plz. I also had another question what is C= absin, what is it use for? Thanx guys, I'm a newbie here, and I was just wondering if you can suggest a basic physics book that I can use. thanx again.
