How to Find the Dot Product of Vectors in 2d and 3d Space

Example #1
Let's find the dot product of vectors in two-dimensional space. The coordinates of both vectors are given by points.
Point A coordinates of vector AB: (5 ; 9)
Point B coordinates of vector AB: (-2 ; 11)
Point C coordinates of vector CD: (0 ; 12)
Point D coordinates of vector CD: (-3 ; 1)

Step by step solution:

Let's calculate the coordinates of the first vector from two points A and B:

AB = {x_B - x_A; y_B - y_A} = {-2 - 5 ; 11 - 9} = {-7 ; 2}

Let's calculate the coordinates of the second vector from two points C and D:

CD = {x_D - x_C; y_D - y_C} = {-3 - 0 ; 1 - 12} = {-3 ; -11}

Find the dot product of vectors: AB and CD

AB ⋅ CD = AB_xCD_x + AB_yCD_y = -7 ⋅ (-3) + 2 ⋅ (-11) = 21 + (-22) = -1

Example #2
Find the dot product of the vectors in two-dimensional space.
The coordinates of the vector a: (5 ; 9)
The coordinates of the vector b: (-1 ; 7)

Step by step solution:

Find the dot product of vectors: a and b

a ⋅ b = a_xb_x + a_yb_y = 5 ⋅ (-1) + 9 ⋅ 7 = -5 + 63 = 58

Example #3
Let's find the dot product of vectors in three-dimensional space. The coordinates of both vectors are given by points.
Coordinates of point A of vector AB: (7; 0.2 ; 69)
Coordinates of point B of vector AB: (-1 ; 0 ; 2/8)
Coordinates of point C of vector CD: (-4 ; -6 ; 2)
Coordinates of point D of vector CD: (3 ; 0 ; 9)

Step by step solution:

Let's calculate the coordinates of the first vector from two points A and B:

AB = {x_B - x_A; y_B - y_A; z_B - z_A} = {-1 - 7 ; 0 - 0.2 ; 2/8 - 69} = {-8 ; -1/5 ; -275/4}

Let's calculate the coordinates of the second vector from two points C and D:

CD = {x_D - x_C; y_D - y_C; z_D - z_C} = {3 - (-4) ; 0 - (-6) ; 9 - 2} = {7 ; 6 ; 7}

Find the dot product of vectors: AB and CD

AB ⋅ CD = AB_xCD_x + AB_yCD_y + AB_zCD_z = -8 ⋅ 7 + (-1/5) ⋅ 6 + (-275/4) ⋅ 7 = -56 + (-6/5) + (-1925/4) = -10769/20 = -538.45

Example #4
Let's find the dot product of vectors in three-dimensional space.
The coordinates of the vector a: (5 ; 1 ; 7)
The coordinates of the vector b: (2 ; 4 ; 6)

Step by step solution:

Find the dot product of vectors: a and b

a ⋅ b = a_xb_x + a_yb_y + a_zb_z = 5 ⋅ 2 + 1 ⋅ 4 + 7 ⋅ 6 = 10 + 4 + 42 = 56
