This department supervises the following degree programs: MATHEMATICS,
*Bachelor of Arts* or *Bachelor of
Science*, *Master of Arts* or *Master of
Science*, *Doctor of Philosophy*; STATISTICS,
*Master of Science*. In addition, the department supervises programs leading to minors in mathematics and to teacher certification
in mathematics at the elementary and secondary levels.

Flexibility of elective courses in mathematics is designed to allow the student to prepare to enter the industrial job market, to enter graduate school or professional school, or to begin a teaching career. Recent Tech mathematics graduates have been employed by companies in aerospace (N.A.S.A., defense), electronics (computers, telecommunications), engineering, finance (banks, brokerage, insurance), government (federal agencies, offices, laboratories), petroleum (geophysical, oil), and transportation (airlines, trucking). Some graduates have entered law school or medical school, while many have pursued graduate degrees at various universities.

The curricula leading to the Bachelor of Arts or Bachelor of Science degrees follow the general patterns described in the Arts and Sciences section of this catalog. Immediately upon declaring a major in mathematics, students should consult with the department's Director of Undergraduate Studies for the design and approval of their individual mathematics degree programs. A typical program includes proficiency in calculus at the level of MATH 2350, plus MATH 2360, 3354, 3360, 4350 and at least two of MATH 4343, 4351, 4354, and 4360. In addition, candidates for the B.A. degree must take at least 6 additional hours of approved electives in mathematics at the 3000-level and above, while candidates for the B.S. degree must take at least 12 additional hours of approved electives in mathematics at the 3000-level and above.

For a major in mathematics, a minimum of 30 to 39 hours of mathematics is required, depending on where the student can start in calculus and which degree the student seeks. Also, a student must have a grade of C or better in each mathematics course counted toward the degree.

Candidates for the B.S. degree must choose their minor from the following: atmospheric science, biology, botany, chemistry, chemical engineering, civil engineering, computer science, economics, electrical engineering, exercise and sport sciences, geosciences, industrial engineering, mechanical engineering, microbiology, petroleum engineering, physics, or zoology. A minor must include 18 semester hours, 6 of which must be advanced, in the minor department. Courses counted for the minor must be approved by the minor department.

In addition to the minor, candidates for the B.S. degree must complete a full year (8 hours) in a laboratory science (biology, botany, chemistry, geosciences, microbiology, physical geography, physics, or zoology).

The Department of Mathematics and Statistics also participates with the Department of Computer Science to offer a Dual Degree Program in Mathematics and Computer Science. This is a five year program. See the Computer Science portion of the catalog for the curriculum, culminating in a B.S. degree in Mathematics from the College of Arts and Sciences, and a B.S. degree in Computer Science from the College of Engineering.

A minor in mathematics requires 18 semester hours, at least 6 of which must be at the 3000-level or above and must be approved by the Director of Undergraduate Studies. The minor sequence is MATH 1351, 1352, 2350, and 2360 plus 6 semester hours of approved courses at the 3000-level or above. Students cannot receive minor credit for both MATH 3350 and 3354. Students must receive a grade of at least C in all courses counted toward a minor in mathematics.

For the minor and major in mathematics at least one half of the upper level mathematics courses must be taken in the Department of Mathematics and Statistics at Texas Tech University. This residency requirement will be waived by the department only in very exceptional circumstances.

** Teacher Education.** The Department of Mathematics and Statistics cooperates with the College
of Education in offering plans for teacher certification in mathematics at both the elementary and the
secondary school levels. The student preparing to teach in the secondary school may select mathematics as a
teaching field and complete the program for teacher certification in mathematics. The student preparing to teach
in the elementary school may select mathematics as an area of academic specialization in elementary
education. The student should consult the Department of Mathematics and Statistics concerning teacher
certification. A student must have a grade of C or better in each mathematics course counted toward elementary
or secondary education certification.

The courses offered in mathematics for students intending to prepare themselves for elementary teaching are MATH 1320, 2370, 2371, 3370, 3371, 4370, and 4371.

The minimum requirements for the teaching field in mathematics (option II) at the secondary level are:

(1) MATH 1351 and 1352 (See Guide for Initial Enrollment in Mathematics) and MATH 2350, 2360, 4331 and 4342;

(2) 6 additional hours to be chosen from MATH 3354, 3360, 3430, 4350, 4362.

** Mathematics Placement.** Placement for students into entry-level mathematics courses (0301-2322) is
based on either appropriate previous prerequisite collegiate mathematics credit or the results of the departmentally
administered Mathematics Placement Examination (MPE). The MPE will be given on the first day of each
summer orientation for students enrolling in the fall and during the open registration periods prior to each semester
and term. Students without appropriate prerequisite collegiate mathematics credit will be placed into entry-level
courses based on the results of the MPE. Students may retake the MPE if necessary. Students who have scored at least
610 on the SATM or at least 26 on the ACTM may enroll in any entry-level mathematics course independent
of whether they have the appropriate previous prerequisite collegiate mathematics credit or the appropriate
MPE score. However, they are encouraged to take the MPE during an orientation session to provide them with a
current assessment of their mathematics skills for advisement purposes.

Students having 6 hours or less of basic mathematics requirements in their degree program may wish to satisfy the requirements by choosing from among these courses: MATH 1320, 1321, 1330, 1331, 1350, 1351, 1352, 2300.

The following list describes the mathematics courses most frequently taken by freshmen:

·MATH 0301 and 0302 are remedial courses and do not carry any degree credit.

Students earning a grade of A or B in MATH 0302 will be eligible to enroll in MATH 1320, 1330, or 1550.

·MATH 1320College Algebra

·MATH 1330Introductory Mathematical Analysis

·MATH 1321Trigonometry

·MATH 1350Analytical Geometry

·MATH 1351Calculus I

·MATH 1550Precalculus

NOTE: Satisfactory score on the placement exam is required for entrance to all above courses. TASP students who have not passed the mathematics section of the TASP Test may not enroll in MATH 1320 or 1321 until they have successfully completed their prescribed program of TASP mathematics skills development. See course listings for descriptions and prerequisites for the courses listed above.
