If N is irrational, then N is not equal to p/q where p and q are integers and q is not equal to 0. Example: √2, √3, √5, √11, √21, π (Pi) are all irrational. Certainly, the real numbers also satisfy the analogous result involving infimum. Theorem 5.46. If \(A\) is a nonempty subset of \(\mathbb{R}\) that is bounded below, then \(\inf(A)\) exists. Our next result, called the Archimedean Property, tells us that for every real number, we can always find a natural number that is larger. To prove this ...R = real numbers includes all real number [-inf, inf]. Q= rational numbers ( numbers written as ratio). N = Natural numbers (all positive integers starting from ...Real Numbers. Given any number n, we know that n is either rational or irrational. It cannot be both. The sets of rational and irrational numbers together make up the set of real numbers. As we saw with integers, the real numbers can be divided into three subsets: negative real numbers, zero, and positive real numbers.The real numbers. In real analysis we need to deal with possibly wild functions on R and fairly general subsets of R, and as a result a rm ground-ing in basic set theory is helpful. We begin with the de nition of the real numbers. There are at least 4 di erent reasonable approaches. The axiomatic approach. As advocated by Hilbert, the real ...
