- Click on the “Calculate” button.
- View the result displayed on the screen, which is the dot product of the two vectors.
The interface is designed for simplicity, making it accessible for both beginners and seasoned professionals alike.
Formula
The formula for calculating the dot product of two vectors can be stated as:
A • B = |A| |B| cos(θ)
Where:
- A and B are the two vectors.
- |A| and |B| are the magnitudes of the vectors.
- θ is the angle between them.
The dot product can also be calculated by multiplying corresponding components of the two vectors and then summing those products:
A • B = x1 * x2 + y1 * y2 + z1 * z2
Example Calculation
Let’s consider two vectors:
A = (2, 3, 4)
B = (5, 6, 7)
Using the dot product formula:
A • B = 2 * 5 + 3 * 6 + 4 * 7
A • B = 10 + 18 + 28 = 56
The dot product of vectors A and B is 56.
Limitations
While the Dot Product Calculator is an invaluable tool, it is important to be aware of its limitations:
- The dot product only applies to vectors in the same dimension.
