1.4 Linear Inequalities in One Variable
... Two inequalities that have exactly the same solution set are called equivalent inequalities. As with equations, one method for solving a linear inequality is to replace it by a series of equivalent inequalities until an inequality with an obvious solution, such as x 7 2, is obtained. We obtain equiv ...

Chapter 3: Vectors in 2 and 3 Dimensions
... How do we draw vectors in n for n 4 ? We cannot draw pictures of vectors in 4 , 5 , 6 etc. What is the point of the nspace, n , for n 4 ? Well we can carry out vector arithmetic in n-space. A6 Vector Addition and Scalar Multiplication in n Geometric interpretation of vectors in n is not possible ...

Later, in Chapter 3, we will generalize many of the ideas developed in this chapter and apply them to a study of vectors in n-space, that is, to vectors in Rn.

Matrices
... multiplication is generally not commutative: that is, if A and B are two matrices, in general AB BA . The significance of this is that the ordering of matrices is important when you’re setting up the calculation of their product. In fact, left multiplication and right multiplication are terms that ...
