Vector Projection of u onto v Calculator
Introduction & Importance
Vector projection is a fundamental concept in linear algebra, enabling us to project one vector onto another. The vector projection of u onto v calculator helps you understand and apply this concept effortlessly.
How to Use This Calculator
- Enter the components of vector u (e.g., 2, 3, 4) in the respective input field.
- Enter the components of vector v (e.g., 1, 2, 3) in the respective input field.
- Click the ‘Calculate’ button to find the vector projection of u onto v.
Formula & Methodology
The formula for vector projection of u onto v is:
projvu = (u · v) / (v · v) * v
Where ‘·’ denotes the dot product of two vectors.
Real-World Examples
Example 1
Given u = (2, 3, 4) and v = (1, 2, 3), the projection of u onto v is calculated as follows:
| Step | Calculation |
|---|---|
| u · v | 2*1 + 3*2 + 4*3 = 2 + 6 + 12 = 20 |
| v · v | 1*1 + 2*2 + 3*3 = 1 + 4 + 9 = 14 |
| projvu | (20 / 14) * (1, 2, 3) = (10 / 7) * (1, 2, 3) = (10/7, 20/7, 30/7) |
Example 2 & 3
Data & Statistics
| Vector u | Vector v | Projection |

Interactive FAQ
What is the difference between vector projection and vector scalar projection?
Vector projection projects one vector onto another, resulting in a vector. Vector scalar projection, on the other hand, results in a scalar (single value) representing the magnitude of the projection.
