It's often represented graphically as an arrow. Then any vector r → coplanar with a → & b → can be uniquely expressed as r → = x a → + y b → for same scalars x & y. That is because if two vectors are parallel and share a common point, they are on the same line. So being coplanar does mean linear dependence (to the basis of a given plane). Colinear is the same idea but more general, the dependence doesn't have to be in a plane, it can be a hyperplane etc. A collinear vector is a vector that occurs when two or more of the supplied vectors occur along the same line in the same direction as one another. They can be expressed in the form a= k b where a and b are vectors and ' k ' is a scalar quantity. There are two methods for this one. Let b and c non-collinear vectors.
