b) Find so that vectors a=2i+3j and b= i-j can be collinear.
I'm not sure but the condition for 2 vectors of beeing collinear is that the coefficient before i and j must be in proportion.
So, math]\alpha[/tex] = 2/3
Hope it's right.
Hi Guys. I don't know if this is the right section but I need some explanation on this (plz?)
a) Prove that a=b-kc and b=b+ka ( ) are collinear (a,b,c have those lines up that represent vectors)
b) Find so that vectors a=2i+3j and b= i-j can be collinear.
I know that these are probably simple but my brain isn't really working well.
Any help greatly appreciated.
