How did u go from the first to the second line ?
If a x b = 0, then a = kb. This is an important result to be memorised.
Ohh thank u!
Vector product = 0, two vectors are parallel to each other, so a = kb
Scalar product = 0, two vectors are perpendicular to each other
That will make it easier to understand and recall any time ✌️
