2. EUCLIDEAN RINGS
... Proof: Suppose p | ab and p does not divide a. Let d be a GCD of p and a. Then d is a unit or d = pu where u is a unit. In the latter case p divides a, a contradiction. Hence d is a unit, and without loss of generality we may take d = 1. Hence pR + aR = R and so 1 = pr + as for some ...

The focus changed from studying specific rings one at the time (like the ring of Gaussian integers Z[i] or the subring of polynomials fixed under the action of a specific group) to studying whole classes of rings simultaneously (like all rings like Z[i] useful in number theory: the so-called Dedekin ...

Rationality and the Tangent Function
... yields a very natural proof that the only rational values of tan kπ/n are 0 and ±1 (Corollary 1 in Section 2). In all, we give four proofs of this fact. Several applications of this fact appear in Section 2. The numbers tan kπ/n, cos kπ/n and sin kπ/n are algebraic over Q and the study of their degr ...

... The idea is to use two perpendicular axes in the plane and to place the real numbers on the horizontal axis and to place i on the vertical axis. The additive combinations of real numbers and multiples of i would then fill out the plane determined by the two axes. The diagram above shows several exam ...

... ≥ 4 is true (multiply both sides of the equation by r(1 − r)) r(1 − r) only if 1 ≥ 4r(1 − r) is true (add 4r2 − 4r to both sides) only if 4r2 − 4r + 1 ≥ 0 is true (factor) only if (2r − 1)2 ≥ 0 is true. However, this last equation is clearly true for all r ∈ R since the square of any real number is ...
