PPT-8.5.3 – Unit Vectors, Linear Combinations

In the case of vectors we have a special vector known as the unit vector Unit Vector any vector with a length 1 direction irrelevant Two special unit vectors we look at the most i 1 0. It is essential that you do some reading but the topics discussed in this chapter are adequately covered in so many texts on linear algebra that it would be arti64257cial and unnecessarily limiting to specify precise passages from precise texts The 1 Motivation A3 A2 Vectors A3 A21 Notational Conventions A4 A22 Visualization A5 A23 Special Vectors A5 A3 Vector Operations A5 A31 Transposition A6 A32 Equality A6 A33 Addition and Subtraction e Ax where is vector is a linear function of ie By where is then is a linear function of and By BA so matrix multiplication corresponds to composition of linear functions ie linear functions of linear functions of some variables Linear Equations Fundamental system in linear algebra : system of linear equations .

What do today’s students need?. vectors and matrices. A vector is a bunch of numbers. A matrix is a bunch of vectors. A vector in space. In space, a vector can be shown as an arrow. starting point is the origin. ending point are the values of the vector. Vector Spaces. MATH . 264 Linear . Algebra. Introduction.
