Solutions Manual for A First Course in Linear Model Theory, 2e by Nalini Ravishanker, Zhiyi Chi, Dipak Dey (All Chapters) 1.1 |a • b| = | − 9| = 9, while kak kbk = √ 6 √ 22 ∼= 11.489 > 9. 1.2 To verify the Cauchy–Schwarz inequality, first see that the inequality holds trivially if a and b are zero vectors. We therefore assume that both a and b are nonzero. Let c be the vector c = xa − yb, where x = b ′b, and y = a ′b. Clearly, c ′c ≥ 0. We express c ′c ...

1.1 Introduction There are two ways to motivate the notion of a vector: one is by means of lists of numbers and subscripts, and the other is by means of certain objects in physics. We discuss these two ways below. Here we assume the reader is familiar with the elementary properties of the field of real numbers, denoted by R. On the other hand, we will review properties of the field of complex numbers, denoted by C. In the context of vectors, the elements of our number fields are called scal...
