Kim Jongerius, Ph.D.
Professor of Mathematics
Ph.D., Colorado State University
M.S., Colorado State University
B.S., Northern Arizona University
Dr. Jongerius holds master's and doctoral degrees in mathematics, but she enjoys other languages as well. In fact, she combined her undergraduate math major with a major in English and a minor in German.
Dr. Jongerius joined Northwestern's faculty in 1993 and received the college's Teaching Excellence Award in 2005. She has published papers in algebraic geometry/commutative ring theory. Her most recent paper, "Rules and Insights: Connecting the Mathematical and Linguistic Abilities of C.S. Lewis," combined math and literature, her two greatest academic loves. She also recently worked with a team of writers from the ACMS (Association of Christians in the Mathematical Sciences) on a book called Mathematics Through the Eyes of Faith, published in the summer of 2011 by HarperOne. Jongerius co-authored three of the chapters: "Infinity," "Dimension," and "Proof and Truth."
- Logic and Discrete Mathematics
Logic and Discrete Mathematics An introduction to the language and logic of mathematical proof via topics in discrete mathematics. Topics will include logic, elementary number theory, basic set theory and methods of mathematical proof (direct proof, indirect proof, induction). Prerequisite: C- or better in MAT112 or permission of instructor. Other topics will be chosen from counting, functions, relations, recursion and graph theory. (3 credits)
- Introduction to Abstract Algebra
Introduction to Abstract Algebra A study of groups, normal groups and factor groups, Cayley's Theorem, rings, ideals, homomorphisms, integral domains, fields, polynomial rings, field extensions and zeros of polynomials. Prerequisite: C- or better in MAT317 or permission of instructor. (3 credits, alternate years, consult department)
- Calculus for Management, Life and Social Sciences
Calculus for Management, Life and Social Sciences A calculus course for non-majors that emphasizes applications and techniques that are of significance in business, biology, health and social sciences. Applications involving both differential and integral calculus are included. Prerequisite: C- or higher in MAT109, or an ACT math score of at least 22 (SAT 520 or above), or permission of mathematics department chair. Does not count toward a math major or minor. (3 credits) (IGE option under Quantitative Reasoning)
- Calculus III
Calculus III A study of the cylindrical and spherical coordinate systems, vectors in two dimensions and three dimensions, vector valued functions, functions of several variables, multiple integration, and vector calculus. Prerequisite: C- or better in MAT211 or permission of instructor. Meets four days per week. (4 credits)
- Linear Algebra
Linear Algebra A study of the algebra of matrices and vector spaces including matrix operations, systems of equations, determinants, properties of real vector spaces, eigenvalues and eigenvectors. Prerequisite: C- or better in MAT112, 180 or permission of instructor. (3 credits)
- Topics in the History of Mathematics
Topics in the History of Mathematics
- College Geometry
College Geometry A study of topics in Euclidean geometry as well as axiomatic systems, non- Euclidean geometry, and projective geometry. Prerequisite: C- or better in MAT180 or permission of instructor. (3 credits, alternate years, consult department)
