vCalc.V3 - V dot U

The Vector Dot Product (V•U) calculatorV3 - V U.png Vectors U and V in three dimensions computes the dot product of two vectors (V and U) in Euclidean three dimensional space.

INSTRUCTIONS: Enter the following:

  • (V):  Enter the x, y and z components of vector V separated by commas (e.g. 4,5,9)
  • (U):  Enter the x, y and z components of vector U separated by commas (e.g. 4,5,9)

Dot Product (d): The calculator returns the dot product of U and V.  The dot product is also called the inner product or the scalar product.

This formula lets the user enter two three-dimensional vectors (V and U)  with X, Y and Z components.   Note the dot product of two unit vectors is equal to the cosine of the angle between the two vectors.
