Let v 1, v 2,…, v r be vectors in R n. A linear combination of these vectors is any expression of the form where the coefficients k 1, k 2,…, k r are scalars. Example 1: The vector v = (−7, −6) is a linear combination of the vectors v1 = (−2, 3) and v2 = (1, 4), since v = 2 v1 − 3 v2.

a feel for the subject, discuss how linear algebra comes in, point to some further reading, and give a few exercises. I have kept the exposition lively and given an overall sense of breadth of application. In short, these topics invite readers to see for themselves that linear algebra … 2018-04-30 Y et because linear algebra is a form of con tin uous rather than.

## In other words, linear combinations. It--so, it means that if I give you a few vectors--yeah look, here's an important--here--now we're getting to some really important vector spaces. Well, R^n--like, they are the most important. But we will be interested in so-in vector spaces that are inside R^n.
