ANTIREQUISITE: Mathematics 2155A.

COURSE OUTLINE: Mathematics 1120B is an introduction to rigorous mathematical thinking. The main purpose of the course is to teach students to understand mathematical reasoning
and write mathematical proofs. There will be regular homework assignments to help the students acquire information and develop the required analytical skills. There will also be
some discussion of applications as time permits. e.g. proving the veracity of a computer program.

TOPICS: logic, proofs, induction, sets, functions, relations, limits, complex numbers, divisibility, polynomials.

LECTURES: MWF 1:30-2:30, NCB 285.

EVALUATION OF STUDENT PERFORMANCE: Grades will be based on assignments, in-class midterms and the final exam.
Assignments: 40%
Two One-Hour, In-Class, Midterm Exams: 10% each. February 12 and March 11, 2016.
MIDTERM#1: Four questions: 1. Set theory proof (4.4). 2. Statements (2.1). 3. Contrapositive and negation of quantified statements (2.10).
4. Two basic proofs about rational numbers; one by direct proof, the other by finding an example (see 5.4)
MIDTERM#2: Four questions: 1. Induction, three parts [15]. 2. An ``odd-even'' proof [10]. 3. A short contradiction proof [5]. 4. A basic proof with sets [5].
This exam is based on material from chapters 3,4,5 and 6.
Final Examination: 40%. Tuesday, April 12 at 9am. TC 201.

IMPORTANT SENATE POLICY:

Students are responsible for ensuring that their selection of courses is appropriate and accurately recorded and that all course prerequisites have been successfully completed. If the student does not have the requisites for a course, and does not have written special permission from his or her Dean to enroll in the course, the student may be removed from the course and it will be deleted from the student's record. This decision may not be appealed. A student will receive no adjustment to his or her fees in the event that he or she is dropped from a course for failing to have the necessary prerequisites.


STATEMENT ON ACADEMIC OFFENCES:

"Scholastic offences are taken seriously and students are directed to read the appropriate policy, specifically, the definition of what constitutes a Scholastic Offence, at the following Web site: http://www.uwo.ca/univsec/handbook/appeals/scholoff.pdf "

"Computer-marked multiple-choice tests and/or exams may be subject to submission for similarity review by software that will check for unusual coincidences in answer patterns that may indicate cheating."


NEW MEDICAL EXCUSE REGULATIONS:

If you are unable to meet a course requirement due to illness or other serious circumstances, you must provide valid medical or other supporting documentation to the Dean's Office as soon as possible and contact your instructor immediately. It is the student's responsibility to make alternative arrangements with their instructor once the accommodation has been approved and the instructor has been informed. In the event of a missed final exam, a "Recommendation of Special Examination" form must be obtained from the Dean's Office immediately.

For further information please see:

http://www.uwo.ca/univsec/handbook/appeals/medical.pdf


A student requiring academic accommodation due to illness, should use the Student Medical Certificate when visiting an off-campus medical facility or request a Record's Release Form (located in the Dean's Office) for visits to Student Health Services.
