|This law states that :|
“The scalar product of two vectors and is equal to the magnitude
of vector times the projection of onto the direction of vector . “
|Consider two vectors and ,the angle between them is q.|
where represents the projection of vector onto the direction of vector .
|Where represents the projection of vector onto the direction of vector .|
|This shows that the dot product of two vectors does not chanfe with the change in the order of the vectors to be multiplied.|
This fact is known as the commutative of dot product.
