WebImportant Notes on Linear Algebra. Linear algebra is concerned with the study of three broad subtopics - linear functions, vectors, and matrices; Linear algebra can be classified into 3 categories. These are elementary, advanced, and applied linear algebra. Elementary linear algebra is concerned with the introduction to linear algebra. WebSince it takes two real numbers to specify a point in the plane, the collection of ordered pairs (or the plane) is called 2‐space, denoted R 2 (“R two”). Figure 1. R 2 is given an algebraic structure by defining two operations on its points. These operations are addition and scalar multiplication. The sum of two points x = ( x 2, x 1) and ...

The dot product is a measure of how similarly directed the two vectors are. For example, the vectors (1,1) and (2,2) are parallel. If you compute the angle between them using the dot product, you will find that θ = 0.
