hi guys just want to clarify something...
If we are givin (vectors w u and v) w=au +bv what can we say about w
a) if u and v are independant?
b) if u an v are dependant?
this is what i got so far.
a) w cannot be writtin as a scalar multiple of u and v and are therefore not coplanar.
b)w can be written as a scalar multiple of u and v and are therefor coplanar.
but i think there is more to it. I don't think my answer explains enough.
in a) can i say that w=0?... just trying to find more properties of w for a) and b)... any help would be appreciated. thnks.
