Symbol for vectors with same direction
$begingroup$
How do you state that two vectors $vec{A}$ and $vec{B}$ have the same direction? I know the symbol $| |$ shows that they are parallel, but is there a symbol like this that shows that the direction of the vectors are equal. I think you would call the two vectors collinear. Is there a symbol to show that two vectors are collinear?

Is there a reason parallel isn't enough? Because that literally means their directions are exactly the same

I’m not sure if there’s a symbol for linear dependence (but there may well be one), but to show it you can write $vec{A}=kvec{B}$ for some (scalar) constant $k$

Generally the word parallel is used for vectors pointing in the same direction, and anti-parallel is used for vectors which are pointing in opposite directions.

Perhaps he means one vector is a nonnegative scalar multiple of the other. That is: the case of equality for the triangle inequality.

@aidangallagher4 yeah that's what I ended up using, I was just wondering if there was a better symbol for it.
