4. Let n be a natural number (a) Prove that -2 ()= ("71). (Hint: consider the cases n 1 and n 2 2 separately.) 3 () (b) Conjecture and prove a similar expression for 3 ()? .n (c) What is
Analyze and prove the running time of the recursive formula T(n) = n2 + 2T(n/2). (hint- first prove that it is O(n2 logn). Next see if you could improve your answer. We used the recursion tree method to analyze the running time of MergeSort. Use this method to analyze each one of the following recursive formulas, and obtain its solution. Assume T(n) = 1 when n ≤ 1. Analyze and prove the running time of the recursive formula T(n) =...
2. If L is a regular language, prove that the language 11 = { uv/ u E 1 , |v|-2) is also regular. (Hint: Can you build an NFA of L1 using an NFA of a language L? Use N, the NFA of the language L)
Problem 30. Prove that N, Z, Q and R are infinite sets. (HINT: Prove by induction on n that is f: NN then (3k N(Vj Nn)k> f(j). Then conclude that f cannot possibly be onto N. A similar strategy works for Z, gq and R as well.)
Prove that every subset of N is either finite or countable. (Hint: use the ordering of N.) Conclude from this that there is no infinite set with cardinality less than that of N.
Numerically compute the integral of (x) = 5 + sin2(x) on the interval [0,지 for n-2, 4, 8, 16, 32, and 64 equally spaced subintervals using the midpoint, trapezoidal, and Simpson 1/3 rule. Compare the results with the exact value of the integral, and determine the order of accuracy for each method based on the n = 32 and n 64 results Perform hand calculations for the n = 2 cases, but develop MATLAB programs to perform the rest of...
By using a constructive method, prove that there is a positive integer n such that n! < 2n By using an exhaustive method, prove that for each n in [1.3], nk 2n. By using a direct method, prove that for every odd integer n, n2 is odd. By using a contrapositive method, prove that for every even integer n, n2
By using a constructive method, prove that there is a positive integer n such that n!
