For finding the scalar multiplication of vectors we need to have the two vectors a, b in the same direction. Since the vectors, a and b are at an angle to each other, the value acosθ is the component of vector a in the direction of vector b. Hence we find cosθ in the dot product or scalar multiplication of two vectors. Meer weergeven The dot product of vectors is also called the scalar product of vectors. The resultant of the dot product of the vectors is a scalar value.
