`vecW = vecV to vecU`
Enter a value for all fields
The Vector Projection calculator computes the resulting vector (W) that is a projection of vector V onto vector U in three dimensional space.
Vector V projected on vector U
INSTRUCTIONS: Enter the following:
- (V) Vector V
- (U) Vector U
Vector Projection (W): The calculator returns the vector in comma separated form.
The Math / Science
To compute the projection of vector V onto vector U:
- Compute the magnitude of vector V
- Compute angle between vectors V and U
- Compute the unit vector of vector U
- Compute the scalar (k) associated with the projection which is the magnitude of V times the cosine of the angle between them.
- Compute the vector resulting in the scalar multiplication of the unit vector of U and the scalar (k).
3D Vector Functions
