complex numbers - Iowa State University

EE 201 complex numbers – 3 Clearly, this number j has some interesting properties: j · j = j2 = –1. j3 = j · j · j = (j · j) · j = (–1) · j = –j. j4 = j2 · j2 = (–1) · (–1) = +1. j5 = j4 · j = (+1) · j = +j. Looking at successively higher powers of j, we cycle through the four values, +j, –1, –j, +1. A number, like jb, that has a negative value for its square, is known as

2.3 Bounds of sets of real numbers - Ohio State University

people.math.osu.edu

The modern approach is to define the set of real numbers through its properties: Definition A set with properties I-V is called the set of real numbers. This is an axiomatic definition: properties I-V are taken to be axioms - statements considered to be true. All other properties of real numbers are deduced from these five, using logic.

The Absolute Value Function, and its Properties

The following properties of the absolute value function need to be memorized. Lemma 1.For any two real numbers x and y, we have jxyj= jxjjyj. This equality can be veri ed by considering cases. One of the four possible cases is checked as follows: Suppose x < 0 and y 0. Then xy is 0 and we have jxyj= (xy) = ( x)y = jxjjyj.

Thus the domain of h(x), which is the domain of (g(x))¡1, is the set of all real numbers x such that g(x) 6= 0, which is precisely what the quotient rule tells us.
