Homework, Exams and Grading:There will be two in-class midterm exams and one final exam. You are welcome and encouraged to discuss homework with other students, but you must write your solutions individually. The course grade will be determined as follows: Homework (25%). Will be assigned every class; due every Friday before class. We will spend a half of each Friday class discussing the solutions. One homework with the lowest score will be dropped.

Analysis, one of the pillars (along with algebra and topology) of modern mathematics, begins with a rigorous development of single-variable calculus. Thus,this course serves the important purpose of teaching you how to rigorouslyprove and apply results in calculus, including results related to the notionsof limit, continuity, derivative, integral, and infinite series. Inherentin all of these notions is the concept of approximation. As we shallsee, a good grasp of this latter concept is essential not only in proving''pure'' results in analysis, but is also crucial in ''applied'' problemsrequiring estimations. In any approximation a key question is ``howdo you estimate the error''? In the first part of this course,we will look at some types of algebraic manipulations that can be usedin error estimation; we will also look at more powerful methods involvingthe mean value theorem for derivatives.Difference between the courses:MAT 320 is more comprehensive and providesa firm grounding for further study. MAT 319 has more of an emphasis ontopics which arise in high-school calculus.Students planning to go on to graduate schoolin mathematics are advised to take MAT 322 and MAT 324 as well.Students wanting to take MAT 322 or MAT 324 (or the seminarsMAT 401 or MAT 402) will need to take MAT 320, not MAT 319. Studentswho want to take these courses after MAT 319 instead will need to do some extrawork, and get permission from the relevant instructor.Prerequisites: C or higher in MAT 200 or permission of instructor;plus one of the following: C or higher in MAT 203, 205, 211, AMS 261, or A- orhigher in MAT 127, 132, 142 or AMS 161. Anyone lacking these prerequisitesrisks deregistration.Instructors: Daryl Geller, 4-100B Math Building,phone 632-8327.

There are solutions for almost every problem in the book.Text for MAT 319, after the first five weeks:R.G. Bartle and D.R. Sherbert, Introduction to Real Analysis, 3rd edition,available in the university bookstore. You can buy it after the split.Grading System: The first midterm, on the first three chapters of thebook (up to page 117) will be given in class on Thursday, October 7.It will be graded by Monday, October 11, at which time the classes will split.You will be allowed to switch your registration from MAT 319 to MAT 320 at that time.Your results on the test will help you to make an informed decision.There will also be a second midterm. In MAT 320, it will be held on Tuesday, November 16. The final examination will be held on Thursday, December 16, from11:15 a.m. - 1:45 p.m.Students are expected to ensure when they register for the courses thatthey will be available for the final examination, and that they donot have too many final exams on that date.The final course grades will be determined as follows:homework 10%, two midterms 25% each, final exam 40%.The grades of A- and A will be reserved for students who demonstrate asubstantial ability to apply the concepts of the course in new andsomewhat creative ways.Please note that there will be no curve in this course indetermining grades. Incompletes will be granted only if documented circumstances beyond yourcontrol prevent you from completing the course work.Homework:The only way to learn the material is to work problems for yourself. Eachweek, you should attempt to do all of the problems from the sectionswhich are covered in class. We will ask you to hand some problems in.Your homework will be graded meticulously and will give you vitalfeedback on where you are making mistakes.Homework is a means to an end, the ``end'' being for you tolearn the material. We encourage you to work on homework togetherwith friends. In this course, we will never prosecute anyone foracademic dishonesty on any issue relating to homework.If you hand in complete, correct solutions, you will get fullcredit for them, no matter how you obtained them. When you hand in homework in this course, you are not claiming that it is your own work.If someone regularly ``does''the homework by copying from friends or from solution manuals, they areonly cheating themselves, since this is not a way to learn the material.Moreover, they will not receive the benefits of the feedback that our meticulous grading will provide.Never be shy to ask us how to do a homework problem, even if you handed in a copied solution that you do not understand. You will not beprosecuted or condemned for this, and we will be only too glad to helpyou.
