(Discrete Math) Read the following combinatorial proof, and write a theorem that we proved. Explain it in details.
We count the number of k+1 element subsets of [n+1]. On one hand, it is clearly C(n+1,k+1). On the other hand, we can count these subsets in two steps. First we count the subsets that contain the number n+1. Since have to choose another k elements from {1,2,...,n} for it to make a k+1-element set, the number of these is C(n,k). Then we count the subsets that do not contain the number n+1. This time, we have to choose all k+1 elements from {1,2,...,n}. The number of these is C(n,k+1).

Problem 3. Earlier this semester, we proved the Fundamental Theorem of Algebra using an application of Liouville's Theorem. This problem asks you to fill in the details of an alternate proof of the Fundamental Theorem of Algebra that uses Rouché's Theorem. Let p(2) = 20 + 01 + a222 + ... + an-12"-1+ anza be a nonconstant polynomial of degree n > 1. (a) First, we choose R large enough so that, if |:| = R, then ao +213 +222+...+an-12"-1...
In the following problem, we will work through a proof of an important theorem of arithmetic. Your job will be to read the proof carefully and answer some questions about the argument. Theorem (The Division Algorithm). For any integer n ≥ 0, and for any positive integer m, there exist integers d and r such that n = dm + r and 0 ≤ r < m. Proof: (By strong induction on the variable n.) Let m be an arbitrary...
Problem 8. (Heap Top-k) Prof Dubious has made the following claim, and has provided a proof Claim. Let n and k be positive integers such that 2*-1n. In amax-heap H of n elements, the top 21 elements are in the first k layers of the heap. Proof. Since is a max-heap, each node in H must satisfy the heap property, i.e., if H, is an element of H with at least one child then Hmaxchldren(H)). We know that every subtree...
1. Both Lagrange's theorem and Cauchy's theorem deal with the relationship between the size of a group and the order of its elements. (a) Explain the difference between the theorems in general terms and by using S7 as an example. Your explanation should include what we can and cannot conclude from each theorem about S7 (b) Which theorem would allow you to prove that if a group contained only elements that had order some power of 2, then the order...

Discreet mathematics Question 19 6 Assemble an inductive proof to show that the quantity 5-1 is a multiple of 4 for all positive integers n Your proof must not contain redundant elements Write your proof on scratch paper first Base Case: Select Select The n-o case is true, since 5' 1 is a multiple F4 The n=1 case true, since 5 1 = 0 is a multiple of 4 The n-2 case true, since 5 -1- 4 is a multiple...
10. Read through the following "e-free" proof of the uniform convergence of power series. Does it depend on limn→oo lan|1/n or lim supn→oo lan! an)1/n? Explain. 1.3 Theorem. For a given power series Σ ak-a)" define the number R, 0 < R < oo, by n-0 lim sup |an| 1/n, then (a) if |z- a < R, the series converges absolutely (b) if lz-a > R, the terms of the series become unbounded and so the (c) if o<r <...
(A and C) Exercise 1.14. If n and k are integers, define the binomial coeffi- cient (m), read n choose k, by n! if 0 <k <n, = 0 otherwise. k!(n - k)! (a) Prove that ("#") = (m) + (-2) for all integers n and k. (b) By definition, () = 1 if k = 0 and 0 otherwise. The recursion relation in (a) gives a computational procedure, Pascal's triangle, for calculating binomial coefficients for small n. Start with...
Hi, I would appreciate any help for this problem I don't really understand for discrete math. Thanks! (: 15. (P5) Remember, an L-tromino is a shape consisting of three equal squares joined at the edges to form a shape resembling the capital letter L. Consider the following "theorem" "Theorem": For any integer n 1, if one square is removed from a 2·2" × 3·2" checkerboard. the remaining squares can be completely covered by L-shaped trominoes. What follows is a supposed...
