If a=3uv,b=u+2v and c=3u+4v where u and v are two nonparallel vectors 1.Draw the vectors on a plane using magnitudes and slope angles 2.Express c in terms of a and b 3.determine the magnitude of the vector d=3a+2b+c.Given that u and v unit vectors inclined at 60°. Help me....!!!!!

It is in the question above a=3uv b=u+2v c=3u+4v

They are two non parallel vector components

We have to start making assumptions if you don't have them. Begging for an answer, however politely, will not get any of us anywhere. Without knowing what u and v are: 1. Is simply impossible. 2. We don't have a unique answer for this. 3. Can't be done until we can solve 2. Dan Last edited by topsquark; December 26th, 2018 at 12:40 PM.
