Any vector has an associated unit vector in the same direction but having a magnitude of one. Any vector can be expressed as ascalar multipleof its unit vector. The following diagram shows how to normalize a vector or how to determine a unit vector. Scroll down the page for more examples...
Vector Algebra:Here we have been given two unit vectors magnitude of which is 1. Magnitude of the sum of the vectors are known to us. We need to find the magnitude of the difference of those two unit vectors. We don't know the angle between those vectors, and we do...
A vector can be thought of an object which carries something from point A to point B. In the image shown above, point A is the initial point and point B is the sense point. Vectors can also be represented using coordinates. In three-dimensions, a general vector may be denoted as v=...
