Suppose we had defined some bijection f : N → Q +.

(a) Discuss how you could use f to prove that Q − is countably infinite. That is, define a new function h : N → Q − that uses f in some way. Discuss why using f makes h itself a bijection.

(b) Discuss how you could show that Q is countably infinite.

Exercise We say that |A| = |B| if there exists a bijection f : A → B. (a) Show that the intervals [1, 2] and [3, 7] have the same cardinality. (b) Show that the intervals (0, 1) and (0, ∞) have the same cardinality. (Hint: First try (0, 1) and (1, ∞) (later subtract 1). Identify numbers small numbers in (0, 1) with large numbers in (1, ∞) somehow.) (c) Show that the interval (0, 1) and the real...

2. The Fibonacci sequence is defined as f(n) = f(n - 1) + f(n - 2)...

2. The Fibonacci sequence is defined as f(n) = f(n - 1) + f(n - 2) with f(0) = 0 and f(1) = 1. Find f(54) by a program or maually. Note that this number must be positive and f(53) = 53.......73 (starting with 53 and ending with 73). I must admit that my three machines including a desktop are unable to find f(54) and they quit during computation. The answer is f(54) = 86267571272 */ The Java code: public...

Suppose f is a degree n polynomial where f(a1) = b1, f(a2) = b2, · · · f(an+1) = bn+1 where a1, a2, · · · an+1 are n + 1 distinct values. We will define a new polynomial g(x) = b1(x − a2)(x − a3)· · ·(x − an+1) / (a1 − a2)(a1 − a3)· · ·(a1 − an+1) + b2(x − a1)(x − a3)(x − a4)· · ·(x − an+1) / (a2 − a1)(a2 − a3)(a2 − a4)·...
