Question

define cross( or vector) products of two vector and write its expansion​

Answer 1

Answer:

The cross product of two vectors a and b is defined only in three-dimensional space and is denoted by a × b. ... If the vectors a and b are parallel (i.e., the angle θ between them is either 0° or 180°), by the above formula, the cross product of a and b is the zero vector 0.
