In nite Series 3 5. 4.State the de nition for a set to be countable. We get the relation p2 = 3q2 from which we infer that p2 is divisible by 3. De nitions (1 point each) 1.For a sequence of real numbers fs ng, state the de nition of limsups n and liminf s n. Solution: Let u N = supfs n: n>Ngand l N = inffs n: n>Ng. The origins of the part of mathematics we now call analysis were all numerical, so for millennia the name “numerical analysis” would have been redundant. If ris rational (r6= 0) and xis irrational, prove that r+ xand rxare irrational. REAL ANALSIS II K2 QUESTIONS : Unit 1 1. 7. Hence p itself is divisible by 3, as 3 is a prime PAPER II– REAL ANALYSIS Answer any THREE questions All questions carry equal marks. (7) If the real valued functions f and g are continuous at a Å R , then so are f+g, f - g and fg. True. Define finite Show that m(p) is a O-ring But analysis later developed conceptual (non-numerical) paradigms, and it became useful to specify the different areas by names. (Mathematics) Subject: MTH-502: Real Analysis Question Bank Ans 1) If the function f (ᑦ) = ᑦ2 is integrable on [0,a] then ∫ ὌᑦὍdᑦ= If f and g are real valued functions, if f is continuous at a, and if g continuous at f(a), then g ° f is continuous at a . Derivatives and the Mean Value Theorem 3 4. 3. Questions (64) Publications (120,340) ... (PDF). Math 312, Intro. to Real Analysis: Final Exam: Solutions Stephen G. Simpson Friday, May 8, 2009 1. Improper Integrals 5 7. Assume the contrary, that r+xand rxare rational. 3.State the de nition of the greatest lower bound of a set of real numbers. Students are often not familiar with the notions of functions that are injective (=one-one) or surjective (=onto). Math 4317 : Real Analysis I Mid-Term Exam 2 1 November 2012 Name: Instructions: Answer all of the problems. In real analysis we need to deal with possibly wild functions on R and fairly general subsets of R, and as a result a rm ground-ing in basic set theory is helpful. Solution. Retrieved 2011-07-23. x for all x2Eand if 0 is any other lower bound for the set Ethen we have that 0 . A … True. QN T.Y.B.Sc. Undergraduate Calculus 1 2. Then limsup n!1 s n= lim N!1 u N and liminf n!1 s n= lim N!1 l N: Real Analysis Math 131AH Rudin, Chapter #1 Dominique Abdi 1.1. (a) For all sequences of real numbers (sn) we have liminf sn ≤ limsupsn. If g(a) Æ0, then f/g is also continuous at a . THe number is the greatest lower bound for a set Eif is a lower bound, i.e. (a) Show that √ 3 is irrational. Limits and Continuity 2 3. “numerical analysis” title in a later edition [171]. Since the rational numbers form a eld, axiom (A5) guarantees the existence of a rational number rso that, by axioms (A4) and (A3), we have 2. Prove that there exists a real continuous function on the real line which is nowhere differentiable. Partial Solutions: 1. Explore the latest questions and answers in Real Analysis, and find Real Analysis experts. The Riemann Integral and the Mean Value Theorem for Integrals 4 6. There are at least 4 di erent reasonable approaches. Sample Assignment: Exercises 1, 3, 9, 14, 15, 20. (b) Every bounded sequence of real numbers has at least one subsequen-tial limit. FINAL EXAMINATION SOLUTIONS, MAS311 REAL ANALYSIS I QUESTION 1. We begin with the de nition of the real numbers. The real numbers. True or false (3 points each). Suppose that √ 3 is rational and √ 3 = p/q with integers p and q not both divisible by 3. very common in real analysis, since manipulations with set identities is often not suitable when the sets are complicated.
