​Dot Product

The Dot product is the result of multiplying two vector quantities. It is often known as a scalar product. This emphasizes the magnitude of the value only. The word scaler predicts that the answer will be scaler quantity rather than vector quantity. However, it deals with the single dimension of the value, rather than the three-dimensional value.


Formula of ​Dot Product Calculator

The dot product is represented by a dot between two values. i.e

A.B = |A| |B| cos(θ)


|A| = magnitude of the vector quantity A

|B| = magnitude of the vector quantity “B”

θ (theta) = angle between A and B

Properties of Dot Product

The characteristics of dot products are as follow:

Distributive Quantity

The value outside the bracket is multiplied by both terms inside i.e.,

A . ( B + c ) = A . B + B . C


Multiplying the values in either order will have the same result. i.e.,

A . B = B . A


The results of combining elements of two vector values in either pattern will be the same. i.e.,

A(RB + C) = R(A . B) + (A . C)

Scalar Multiplication

In scalar multiplication, you can take the common values inside the bracket. i.e.,

(C1A) . (C2B) = C1C2 (A . B)


Calculate the dot product of vectors A and B, where A = 8, B = 15, θ = 60°.

Given data

A = 8
B = 15
θ = 60°

To Find

A.B = ?


As we know,

A.B = |A| |B| cos(θ)

Putting values in the formula:

A.B = (8) (15) cos(60)
A.B = (120) (0.5)
A.B = 60

Therefore, the dot product of vectors A and B is A.B = 60
