Enter a value for all fields

The **Vector Area** calculator * Vectors U and V in three dimensions* computes the area swept between two vectors (V and U) in Euclidean three dimensional space. This is the light blue area in the graphic.

**INSTRUCTIONS:** Enter the following in meters:

- (
**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)

**Area between Vectors (A): **The calculator returns area in square meters. However, this can be automatically converted to compatible units via the pull-down menu.

The Area between two Vectors (A) calculator computes the two dimensional area between two 3D vectors. The formula to compute the area is:

- Compute the length (magnitude) of both vectors. They represent the length of two legs of a triangle (|V| and |U|).
- Compute the angle between the vectors(α).
- Use the two lengths of and the angle to compute the area of the triangle, where:

A = 1/2 ⋅ |V| ⋅ |U| ⋅ sin(α)

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.
