Concept explainers

Magnitude

A vector is an element with both direction and magnitude. A vector is represented using an arrow, where the arrow represents the direction of the vector and its length is represented using the magnitude. The set of vectors in space is known as vector space. The vectors can be added, subtracted, multiplied, and divided in a vector space. The image below shows a vector AB.

Question

2. Define the scalar product of two vectors (show both methods, algebraic (using components) and geometric (
using the angle)). Calculate the interior angles of you triangle ABC using the scalar product and show that they
add to 180".
