discrete math. Structural Induction: Please write and explain clearly. Thank you. Let S be the set of binary strings defined recursively as follows: Basis step: 0ES Recursive step: If r ES then 1rl E S and 0x0ES (I#x and y are binary strings then ry is the concatenation of and y. For instance, if 011 and y 101, then ry 011101.) (a) List the elements of S produced by te first 2 applications of the recursive definition. Find So, Si...
PROVE BY INDUCTION Prove the following statements: (a) If bn is recursively defined by bn = bn-1 + 3 for all integers n > 1 and bo = 2, then bn = 3n + 2 for all n > 0. (b) If an is recursively defined by cn = 3Cn-1 + 1 for all integers n > 1 and Co = 0, then cn = (3” – 1)/2 for all n > 0. (c) If dn is recursively defined by...

(b) Let S be the subset of the set of ordered pairs of integers defined recursively by: Basis Step: (0,0) ES, Recursive Step: If (a, b) ES, then (a +2,5+3) ES and (a +3,+2) ES. Use structural induction to prove that 5 (a + b), whenever (a, b) E S. Show all your work.
Suppose the language L ? {a, b}? is defined recursively as follows: ? L; for every x ? L, both ax and axb are elements of L. Show that L = L0 , where L0 = {aibj | i ? j }. To show that L ? L 0 you can use structural induction, based on the recursive definition of L. In the other direction, use strong induction on the length of a string in L0. 1.60. Suppose the language...
7) Define a set U of strings of a, b, and c recursively as follows: B. bEU R. If XEU, then axc EU. List four elements of U and apply structural induction to show that every element in U is in the form of a"bc", where n is a non-negative number

11: I can identify the predicate being used in a proof by mathematical induction and use it to set up a framework of assumptions and conclusions for an induction proof. Below are three statements that can be proven by induction. You do not need to prove these statements! For each one clearly state the predicate involved; state what you would need to prove in the base case; clearly state the induction hypothesis in terms of the language of the proposition...
The Fibonacci numbers are defined as follows, f1=1, f2=1 and fn+2=fn+fn+1 whenever n>= 1. (a) Characterize the set of integers n for which fn is even and prove your answer using induction (b) Please do b as well. The Fibonacci numbers are defined as follows: fi -1, f21, and fn+2 nfn+1 whenever n 21. (a) Characterize the set of integers n for which fn is even and prove your answer using induction. (b) Use induction to prove that Σ. 1...
a)Write a Python function product(a, b) that recursively computes and returns the value of a times b. Use only the addition operator, and do not use any loops. You can assume that both parameters are non-negative integers. b)Use induction to prove that your algorithm from the previous part is correct
