By the above S / (f). By the Principle of Induction, let no be its smallest element. Then a(no — 1) < b < ano- Let r = b — a(no — 1). Then b = na + r and 0 < r. If r > a, then b — a(no — 1) > a; so we would get b > an0, a contradiction. 2. Show that for a fixed a and b, the n and r in the Euclidean algorithm are unique. We now define a prime number. This is a positive integer, p, greater than 1 which can't be factored into a product of two or more numbers in Z + (except for the trivial factorization p = p • 1).

The angle 9, in radians, between the line from the origin through A (a point on the unit circle) and the positive x axis is called the argument of z, written 34 Chapter 1 What is a Number? arg(z), while \z\ > 0 is called the modulus. Clearly, \z\ is uniquely determined by z and arg(,z) is uniquely determined up to an integer multiple of 2ir. In fact, because of the definitions of sin and cos we see that z —- = cos 8 + i sin 6. 10 z. Here we write z = |z|(cos# + ismO). 5 We now prove (DeMoivre's theorem) \zw\ = \z\\w\ and arg(2;u;) = arg(z) + arg(u;).

Let u = cos 2n 1-K \- % sin — . n n By DeMoivre's theorem, we get ujn = 1, but for j = 1 , . . , n — 1 we see that wJ ^ 1 since 0 < - ^ < 2ir and so it doesn't even have the right argument to be 1. It follows that the set of all powers S = {u, u2,.. a;"}, called the nth roots of unity are distinct. For if w-7 = uok where I < j < k < n, then we would get ujk~i = 1, a contradiction, since 1 < k — j < n. Moreover, for j = 1 , . . , n each wJ has the property that 36 Chapter 1 What is a Number?
