What is a unit vector?

A unit vector has magnitude 1 and points in the same direction as the original vector. It is found by dividing each component by the magnitude.

How do you add vectors?

Add corresponding components: (ax+bx, ay+by, az+bz).

Enter two vectors (A and B) to compute their magnitudes, unit vectors, sum (A + B), and difference (A - B). Supports 2D and 3D vectors.
