Introduction
The Department of Mathematics offers majors and minors in mathematics, applied mathematics and mathematics education. Combined majors are offered in mathematics and computer science, biology and mathematics, chemistry and mathematics, economics and mathematics, and physics and mathematics. The department also offers a Master of Science degree.
By taking a significant number of graduate math courses as an undergraduate, it is possible to earn both a Bachelor of Science and a Master of Science degree in mathematics within a total of five years of study. Detailed requirements for this option are available from the Department of Mathematics.
The majors mentioned above will serve as components of a liberal education, but each one also prepares the recipient for a career in business, industry, government or education. Further information about career opportunities is available in the department office or website. Persons planning a career in almost any field will find their opportunities for interesting and challenging positions enhanced by the study of mathematics. A person who develops the ability to formulate and solve quantitative problems will be able to attack many of the complex problems of the world.
Mathematics
Mathematics has developed from attempts to find simple general laws governing the behavior of the phenomena we observe around us; phenomena as diverse as the motion of the planets, the evolution of biological systems and the movement of traffic.
These attempts have been remarkably successful, although many problems remain to be solved. The concepts involved are profound and exciting; their development and use require imagination and careful deductive reasoning.
Mathematics reveals hidden patterns that help us understand the world around us. Now much more than arithmetic and geometry, mathematics is a diverse discipline that deals with data, measurements, and observations from science, with inference, deduction, and proof; and with mathematical models of natural phenomena, human behavior, and social systems.
As a practical matter, mathematics is a science of pattern and order. Its domain is not molecules or cells, but numbers, chance, form, algorithms, and change. As a science of abstract objects, mathematics relies on logic rather than on observation as its standard of truth, yet employs observation, simulation, and even experimentation as means of discovering truth.
The special role of mathematics in education is a consequence of its universal applicability. The results of mathematics — theorems and theories — are both significant and useful; the best results are also elegant and deep. Through its theorems, mathematics offers science both a foundation of truth and a standard of certainty.
In addition to theorems and theories, mathematics offers distinctive modes of thought which are both versatile and powerful, including modeling, abstraction, optimization, logical analysis, inference from data, and use of symbols. Experience with mathematical modes of thought builds mathematical power — a capacity of mind of increasing value in this technological age that enables one to read critically, to identify fallacies, to detect bias, to assess risk, and to suggest alternatives.
Mathematics empowers us to understand better the informationladen world in which we live.

© 1989, National Academy of Sciences
The purpose of the mathematics and applied mathematics majors is to acquaint the student with mathematical concepts; to provide the student with the tools needed to apply the concepts in other fields; and to continue to learn and develop new ideas.
A student primarily interested in the application of mathematical ideas in another field should elect the major in applied mathematics or one of the combined majors. A student who is interested in some branch of mathematics itself, or who is considering graduate study in mathematics, should choose the mathematics major. A student considering a career as an actuary should consult the department website for specific course suggestions. A student who is unsure about future plans should probably consult the department website for a mathematics major and adviser.

Declaration Process
Students who intend to complete a major in the department are urged to declare the major formally at an early point in their Western career so that a program of study can be planned in collaboration with a departmental advisor. This does not in any way decrease the opportunity to change plans, but does ensure constructing an efficient program which is not subject to future catalog revisions.
Departmental Honors
The mathematics department offers two means of recognition for outstanding students. One, Graduation with Merit in Mathematics, is an award which recognizes outstanding scholastic achievement in courses required for the major. The second, Graduation with Distinction in Mathematics, is a program which rewards exceptional achievement in mathematics as evidenced by meeting all the requirements for Graduation with Merit and completing certain additional requirements detailed below. While Graduation with Merit is automatically conferred on all students who qualify, students must apply to the Chair of the Department of Mathematics to participate in the program for Graduation with Distinction in Mathematics.
Students interested in these programs should also inquire into the possibility of earning both a Bachelor of Science and a Master of Science degree in mathematics within five years of study. Detailed requirements for this option are available from the Department of Mathematics.
Graduation with Merit
To graduate with Merit in mathematics, a student must complete one of the majors or combined majors offered by mathematics alone or by mathematics in cooperation with another department.
The student’s program must include at least 32 quarter hours of mathematics or mathcomputer science courses taken at Western, including MATH 225, 304 and 312 and at least 23 approved credits at the 400 level or above. The cumulative GPA for mathematics and mathcomputer science classes taken at Western must be at least 3.6.
Graduation with Distinction
To graduate with Distinction in mathematics, a student must meet all the requirements for graduation with Merit in mathematics.
Furthermore, the student must successfully complete:
 A comprehensive examination covering MATH 124, 125, 224, 225, 226, 204, 331
 An approved senior project
The comprehensive examination should be taken no later than the junior year. This examination may be retaken if necessary, but must be passed no later than fall of the senior year and before beginning the senior project.
The senior project is subject to approval of the Undergraduate Committee and is undertaken under the direction of a faculty member. It includes some independent work, the preparation of a report and a colloquium presentation. The senior project constitutes a course at the 400 level and is letter graded with 4 credits applicable towards the major.
Students interested in graduating with Distinction in mathematics should declare their interest to the Chair of the Department of Mathematics at an early point in their career at Western in order to receive appropriate advice and guidance.
Other Departmental Information
Mathematics Education
The Bachelor of Arts in Education major may be completed with either of two concentrations; one prepares the graduate for teaching mathematics on the secondary level, the other concentrates on the elementary level. Those who intend to pursue one of these concentrations must complete certain courses in calculus, linear algebra, discrete mathematics, statistics, number theory, geometry, the history of mathematics, and computer science. Successful completion of these courses provides a good part of the training necessary for technical expertise in the classroom.
The elementary concentration emphasizes breadth in mathematics. Breadth of experience is important so that the teacher can expose elementary students to a wide variety of mathematical topics. The specialist in mathematics on the elementary level must be particularly skilled at transforming the material mastered in college to a form suitable for the level in question.
Secondary majors learn the methods of teaching mathematics in MATH 483; elementary majors learn such methods in MATH 381, 382, 383 and 491.
Students who wish to teach mathematics on the secondary level also can gain certification in mathematics by completing any one of the Bachelor of Science majors in mathematics, applied mathematics or mathematicscomputer science. In addition to the requirements for the major, they are expected to complete these courses: MATH 302, MATH 360, MATH 419 and MATH 483.
Recommendation for teaching endorsement requires the completion of the major with a minimum grade point average of 2.50 in the courses required for the major. The state of Washington requires a minimum grade of C (2.0) or better for all courses used to meet major certification or endorsement requirements. To gain the Initial Teaching Certificate, students must also complete a program of studies in professional education, including student teaching. Early in their careers at Western students should seek formal advisement on the appropriate program in education. It is essential that the interested reader consult the Elementary Education and Secondary Education sections of this catalog for further information.
Academic Placement
Initial placement in most mathematics courses at Western is on the basis of the results of an appropriate placement test, except for some students who have successfully completed at least one quarter of calculus or precalculus in college. Full information on which test to take and how to take it is available from the admissions office or the mathematics department. Mathematics placement tests are administered throughout the state of Washington each year, and both freshmen and transfer students who are residents in Washington are advised to take the appropriate examination prior to arrival on campus.
Students who have completed at least one year of high school calculus or at least one quarter of college calculus should consult a departmental advisor before registering.
Except by permission of the chair of the Department of Mathematics, a student may not receive credit for any of MATH 101, 106, 107, 112, 114, 115, 118, 156 or 157 if that course is completed after completion of any higher numbered course in this list or after completion of a course in calculus for which college credit has been received.
Advice to Entering Students
The Bachelor of Science degrees in mathematics, applied mathematics and mathematicscomputer science are based on the following core:
The Bachelor of ArtsSecondary Education degree has the same core except for
These courses, except for MATH 304 and MATH 312, represent the minimum that a student planning one of these majors should complete during the first two years. A wellprepared student will be able to build a stronger program, possibly including some graduatelevel courses in the senior year, by completing MATH 225 some 300level work chosen under advisement in addition to the list above. In particular, Math 331 (differential equations) will be suitable for many students.
Transfer students, especially those intending to enter Western with an Associate of Arts degree, should normally complete as much as possible of the core program above prior to entering Western, and certainly including the entire calculus sequence and linear algebra. Students should be aware that 200level differential equations courses may not transfer as equivalent to MATH 331, and that certain third quarter calculus courses also may not transfer as equivalent to either MATH 224 or 226.
The Bachelor of Arts major in mathematics provides exposure to a wide range of courses but, relative to the Bachelor of Science major, has fewer requirements for courses in analysis and other upperdivision courses. A Bachelor of Science major in mathematics is generally more appropriate than a Bachelor of Arts major in mathematics for students intending to pursue graduate studies in any mathematically intensive discipline.
Instructors in many courses require that students use a graphing calculator. Students should contact the department for recommendations before purchasing a calculator.
Statistics students should plan to take MATH 342 as soon as possible, preferably well before the end of their sophomore year. The following classes are prerequisites for MATH 342: MATH 124, MATH 125, MATH 204, and MATH 341.
Students interested in becoming actuaries should contact the Math department as soon as possible for advising. The Society of Actuaries has a number of requirements that can be fulfilled at Western, but these requirements don’t fit neatly into any of our existing degrees.
Students interested in pursuing graduate studies in statistics should strongly consider taking MATH 312, MATH 421, and MATH 422.
