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 . 7. Questions (64) Publications (120,340) ... (PDF). (b) Every bounded sequence of real numbers has at least one subsequen-tial limit. Undergraduate Calculus 1 2. REAL ANALSIS II K2 QUESTIONS : Unit 1 1. Limits and Continuity 2 3. “numerical analysis” title in a later edition [171]. (7) Sample Assignment: Exercises 1, 3, 9, 14, 15, 20. True. But analysis later developed conceptual (non-numerical) paradigms, and it became useful to specify the different areas by names. A … Suppose that √ 3 is rational and √ 3 = p/q with integers p and q not both divisible by 3. The Riemann Integral and the Mean Value Theorem for Integrals 4 6. We get the relation p2 = 3q2 from which we infer that p2 is divisible by 3. Then limsup n!1 s n= lim N!1 u N and liminf n!1 s n= lim N!1 l N: 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. Hence p itself is divisible by 3, as 3 is a prime THe number is the greatest lower bound for a set Eif is a lower bound, i.e. FINAL EXAMINATION SOLUTIONS, MAS311 REAL ANALYSIS I QUESTION 1. 3.State the de nition of the greatest lower bound of a set of real numbers. 4.State the de nition for a set to be countable. (a) For all sequences of real numbers (sn) we have liminf sn ≤ limsupsn. 2. 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. Define finite Show that m(p) is a O-ring If the real valued functions f and g are continuous at a Å R , then so are f+g, f - g and fg. to Real Analysis: Final Exam: Solutions Stephen G. Simpson Friday, May 8, 2009 1. True. (10 marks) Proof. Students are often not familiar with the notions of functions that are injective (=one-one) or surjective (=onto). We begin with the de nition of the real numbers. very common in real analysis, since manipulations with set identities is often not suitable when the sets are complicated. 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. Prove that there exists a real continuous function on the real line which is nowhere differentiable. SAMPLE QUESTIONS FOR PRELIMINARY REAL ANALYSIS EXAM VERSION 2.0 Contents 1. If g(a) Æ0, then f/g is also continuous at a . (Mathematics) Subject: MTH-502: Real Analysis Question Bank Ans 1) If the function f (ᑦ) = ᑦ2 is integrable on [0,a] then ∫ ὌᑦὍdᑦ= PAPER II– REAL ANALYSIS Answer any THREE questions All questions carry equal marks. Real Analysis Math 131AH Rudin, Chapter #1 Dominique Abdi 1.1. Assume the contrary, that r+xand rxare rational. The axiomatic approach. There are at least 4 di erent reasonable approaches. (a) Show that √ 3 is irrational. Math 312, Intro. In nite Series 3 5. 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 If ris rational (r6= 0) and xis irrational, prove that r+ xand rxare irrational.
