11. Let an >0 and assume that bn = n+1 + B. What can we say about the convergence of an? an
2. Let a be a positive real number, let r be a real number satisfying r >1, let N be an integer greater than one, and let tR -R be the integrable simple function defined such that tr,N(r) = 0 whenver x < a or z > ar*, tr,N(a) = a-2 and tr,N(z) = (ar)-2 whenever arj-ıく < ar] for some integer j satisfying 1 < j < N. Determine the value of JR trN(x) dz.
Recall that Etan E R is positive if the following two conditions hold: There exists N E Z+ such that an >0 for alln2 N. We use the notation R+to denote the set of positive real numbers: R+ = { E{a») R : Efe») is positive} 1. In class, we proved that the relation<on R, given by is an order relation. In this problem, you'll prove that R satisfies the axioms of an ordered field (a) If E(anh E{놔,Ep., }...
12. Prove that if n >m then the number of m-cycles in Sis given by nn-1)(n-2)... (n-m+1)
The Ackermann function is usually defined as follows: In+1 A(m, n) = {Am - 1,1) ( Alm – 1, A(m, n - 1)) if m =0 if m >0 and n=0 if m >0 and n > 0. Use the definition of the Ackermann function to find Ack(3,2). Please show your work step by step.
1. Recall the following theorem. Theorem 1. Let a, b, m,n e N, m, n > 0 and ged(m,n) = 1. There erists a unique r e Zmn such that the following holds. x = a (mod m) x = b (mod n) please show that such solution is unique.
Problem 3. Prove that if bn + B and B < 0, there is an N E N such that for all n > N, bn < B/2.
Exercise 5. Prove that if f is a continuous and positive function on (0,1], there exists 8 >0 such that f(x) > 8 for any x € [0,1].
Prove that is an integer for all n > 0.
Roots (20 points). Consider the loop-gain transfer function L(S) = TS-a)n-m where n and m are integers such that n > m and a € R. Also, consider the characteristic equation 1+ KL(S) = 0, with 0 <KER, which can be equivalently written as nam (s– an-m + K = TI (s – rj) = 0. Show that num ri=(n - m), for any 0 <KER.
