Ok A is a vector and B is a vector to find the dot product doI find its components or just plug and chug A*B = A(Bcos)?What is the difference between componets and scalars? Do componentsonly depend on when adding vectors? What is the difference between the vector product and aScalar?

Explanation / Answer
if we have the values of the magnitudes of the vectors A and Band the angle between them then it is better to use A*B =AB(cos) if we have in the component form then it is better to usecomponent multiplication.
