## Mathematics

"For the things of this world cannot be made known without a knowledge of mathematics.''--Roger Bacon

Virtually every studentt at UW will take one or more math courses to fulfill grduation requirements. The intent is to illustrate the esthetics inherent in mathematics, and to provide students with the quantitative skills needed for today's careers.

Mathematics majors receive a broad and deep view of the mathematical sciences. They develop their mathematical thinking and communications skills in algebra, analysis, and applied math. They learn a variety of technological tools necessary for jobs in education, business, government, and industry. In addition to our math classes, the department offers a variety of experiences to enrich the undergraduate experience. Students can participate in weekly seminars, summer research projects, Putnam Team competitions, and the math club.

### Mathematics Placement

All UW math courses have prerequisites which are detailed in the course listings below. These are to assure that each student has the best possible opportunity for success in the course. In accordance with this, all students registering for a math course will have their records checked in order to determine whether the prerequisite is satisfied.

A computerized prerequisite check is run prior to the start of every semester. Students who pre-registered for a math course but have not satisfied the prerequisites at the time of the check will be automatically dropped from the course.

Prerequisites for courses numbered 2200 or lower, and 2350 (Business Calculus), may be satisfied in one of four ways:

- Obtain a grade of C or better in a prerequisite course. Note that non-credit courses from out-of-state colleges are not accepted as prerequisites.
- Pass the Mathematics Placement Exam (MPE) at the stated level within one year of the start of the course.
- Obtain a sufficiently high score on one of the following standardized exams within three years of the start of the course: ACT composite math score, SAT quantitative score, GRE quantitative score.
- Obtain a sufficiently high score on one of the following standardized exams: AP Calculus, CLEP, or IB.

More information on mathematics placement may be obtained from the Center for Advising on Mathematics Placement (CAMP), 30 Ross Hall, 766-6577, or at www.uwyo.edu/mpe.

### Duplication of Courses

To avoid loss of credit because of duplication of course content, please note the following: (a) students who have taken MATH 1450 should not take MATH 1400 or MATH 1405; (b) students who have taken MATH 1400 and MATH 1405 should not take MATH 1450; (c) students who have had MATH 1400 may enroll in MATH 1450; however, only two additional hours of credit will be granted.

### Undergraduate Major

A degree in mathematics should prepare students to enter either graduate studies or the workforce with a skill set that could only come from an intense study of both quantitative reasoning and rigorous proof. This can be accomplished by focusing on the following goals for our undergraduate major:

- Develop mathematical thinking and communication skills
- Develop skills with a variety of technological tools
- Provide a broad view of the mathematical sciences
- Require study in depth

The required lower division core courses for a mathematics major are Calculus 1, 2, and 3 (MATH 2200,2205,2210), Differential Equations (MATH 2310), Linear Algebra (MATH 2250), and the Math Major Seminar (MATH 2800).

At the upper division, all mathematics majors must take Analysis 1 (MATH 3205), Algebra 1 (MATH 3500) and Introduction to Scientific Computing (MATH 3340). These courses, known as the transition courses, introduce students to the three main areas of mathematics research currently represented in the department.

Every mathematics major must select one two-course sequence (MATH 4200/4205, MATH 4510/4520, or MATH 4340/4440) that builds on the corresponding transition course. This sequence provides the student with an opportunity to study one of these areas in greater depth.

Finally, an additional 12 credits of upper division courses (3000 and above) are required. It is recommended that these courses be selected to provide a broad view of mathematics.

### Undergraduate Minor

The minor in mathematics focuses on fundamental aspects of mathematics that are essential for further study in mathematics and also useful in a variety of other disciplines. Students minoring in mathematics may customize the minor by choosing the appropriate transition course and upper-division electives to match their needs.

The required lower division core courses for a mathematics minor are Calculus 1, 2, and 3 (MATH 2200,2205,2210), Differential Equations (MATH 2310), Linear Algebra (MATH 2250), and the Math Major Seminar (MATH 2800).

At the upper division, all mathematics minors must take ONE of Analysis 1 (MATH 3205), Algebra 1 (MATH 3500) or Introduction to Scientific Computing (MATH 3340), as well as 6 additional credits of upper division courses (3000 and above).

### Undergraduate Interdisciplinary Computational Science Minor

In recognition of the importance of modeling and simulation in an increasing number of applications, the Undergraduate Interdisciplinary Computational Science Minor is intended to help prepare science, math, and engineering students for leading roles in their professions.

The undergraduate minor in Computational Science is based on the following requirements:

- The student must earn 15 credit hours in specified courses.
- Within the 15 credits, the student must earn 9 credits at the upper-division level (3000 or above).
- Within the 15 credits, the student must earn 6 credits outside of her/his major.
- Within the 15 credits, the student must earn at least 6 credits in core courses.
- Only grades of C or better will be accepted for the minor.

The 15 hours of coursework are divided between core and elective courses as listed below.

#### Core Courses

## Graduate Study

The Department of Mathematics offers programs leading to the degrees of master of arts, master of science, master of arts in teaching, master of science in teaching, and the doctor of philosophy.

The degrees and their requirements reflect our belief that mathematicians should have a broad foundation in the core areas of algebra, analysis, and applied mathematics, as well as the experience of a more intensive investigation of a specialized area. We provide this within a flexible structure that recognizes the individual interests and varied backgrounds of our students.

### Program Specific Admission Requirements

The GRE is required, with a minimum Quantitative Reasoning Score of 155 for master's applicants and 157 for Ph.D. applicants. The Verbal Reasoning Score is also given high consideration but does not have a minimum. The GRE is not required if the applicant has an M.S. or Ph.D. from an approved institution.

Upper-division undergraduate courses in abstract algebra, matrix theory, and two semesters of analysis are recommended. Students who enter with a deficiency in these courses may take them at UW but cannot count them towards a graduate degree.

Serious consideration is given to applicants from a variety of backgrounds, including science, engineering, computer science, statistics and philosophy.

The GRE subject test in mathematics (or in the undergraduate major if not math) may be helpful, but is not required.

### Additional Program Requirements for International Admission

International applicants are required to take the TOEFL exam and earn a minimum score 76 on the iBT. The TOEFL requirement may be waived if a student comes from an English speaking country or has earned a degree from an accredited institution with instruction in English within a year of applying. ETS reports only TOEFL scores taken within two years of date of request.

### Requirements for Admission for M.A.T. or M.S.T.

Applicants are required to have:

- Valid teaching endorsement in any state, or educational requirements satisfied for secondary teaching.
- Two years' teaching experience at the pre-college level (may be completed during degree program).
- Courses equivalent to MATH 3000 or 3200, 3500 or 3550, 4000, and 4600. Students who enter with a deficiency in these courses must take them at UW but cannot count them towards the degree.
- A course in computer programming.
