PAPER II– REAL ANALYSIS Answer any THREE questions All questions carry equal marks. Sample Assignment: Exercises 1, 3, 9, 14, 15, 20. Assume the contrary, that r+xand rxare rational. If the real valued functions f and g are continuous at a Å R , then so are f+g, f - g and fg. The axiomatic approach. Undergraduate Calculus 1 2.

Math 4317 : Real Analysis I Mid-Term Exam 2 1 November 2012 Name: Instructions: Answer all of the problems. QN T.Y.B.Sc. 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. 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. 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. Derivatives and the Mean Value Theorem 3 4. But analysis later developed conceptual (non-numerical) paradigms, and it became useful to specify the diﬀerent areas by names. True. (10 marks) Proof. Solution. 4.State the de nition for a set to be countable. 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 . REAL ANALSIS II K2 QUESTIONS : Unit 1 1. THe number is the greatest lower bound for a set Eif is a lower bound, i.e. “numerical analysis” title in a later edition [171]. to Real Analysis: Final Exam: Solutions Stephen G. Simpson Friday, May 8, 2009 1. If g(a) Æ0, then f/g is also continuous at a . Define finite Show that m(p) is a O-ring FINAL EXAMINATION SOLUTIONS, MAS311 REAL ANALYSIS I QUESTION 1. (b) Every bounded sequence of real numbers has at least one subsequen-tial limit. Limits and Continuity 2 3. SAMPLE QUESTIONS FOR PRELIMINARY REAL ANALYSIS EXAM VERSION 2.0 Contents 1. 3. We get the relation p2 = 3q2 from which we infer that p2 is divisible by 3. Prove that there exists a real continuous function on the real line which is nowhere differentiable. Improper Integrals 5 7. very common in real analysis, since manipulations with set identities is often not suitable when the sets are complicated. 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. There are at least 4 di erent reasonable approaches. x for all x2Eand if 0 is any other lower bound for the set Ethen we have that 0 . (7) Real Analysis Math 131AH Rudin, Chapter #1 Dominique Abdi 1.1. 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 Partial Solutions: 1. (a) For all sequences of real numbers (sn) we have liminf sn ≤ limsupsn. We begin with the de nition of the real numbers. Retrieved 2011-07-23.
