Formula Used in “Angle Between Two Vectors Calculator”

The angle θ between two vectors can be calculated using the following formula:

θ = cos⁻¹((A · B) / (|A| |B|))

Step-by-Step Breakdown of the Formula

In this formula, the following variables are used:

  1. θ: The angle between the two vectors, measured in degrees or radians.
  2. A: The first vector represented as A = (a1, a2, a3), where a1, a2, a3 are the components of the vector in three-dimensional space.
  3. B: The second vector represented as B = (b1, b2, b3), where b1, b2, b3 are its respective components.
  4. A · B: The dot product of vectors A and B, calculated as A · B = a1*b1 + a2*b2 + a3*b3.
  5. |A|: The magnitude (length) of vector A, calculated as |A| = √(a1² + a2² + a3²).
  6. |B|: The magnitude of vector B, calculated as |B| = √(b1² + b2² + b3²).

Example Calculation

Let’s illustrate how to use the formula through a practical example.

Suppose we have two vectors:

  • A = (3, 4, 0)
  • B = (4, -2, 1)
Variable Value
A (3, 4, 0)
B (4, -2, 1)

Calculating the Dot Product

First, we calculate the dot product A · B:

A · B = 3*4 + 4*(-2) + 0*1 = 12 – 8 + 0 = 4

Calculating the Magnitudes

Next, we compute the magnitudes:

|A| = √(3² + 4² + 0²) = √(9 + 16 + 0) = √25 = 5

|B| = √(4² + (-2)² + 1²) = √(16 + 4 + 1) = √21 ≈ 4.58

Final Calculation of the Angle

Now we substitute these values back into the angle formula:

θ = cos⁻¹(4 / (5 * 4.58))

θ = cos⁻¹(4 / 22.9) ≈ cos⁻¹(0.174) ≈ 80.05°

Conclusion

The angle between vectors A and B is approximately 80.05°.
