ühikuvektorid
Ühikuvektorid, also known as unit vectors, are vectors with a magnitude of one. They are used to indicate direction in a vector space. A unit vector in the same direction as a given non-zero vector v can be found by dividing v by its magnitude, denoted as ||v||. The formula for a unit vector u in the direction of v is u = v / ||v||.
In Cartesian coordinates, the standard basis vectors are the unit vectors that point along the positive x,
Unit vectors are crucial in many areas of physics and engineering, such as describing forces, velocities, and
