Kim Jongerius Professor of Mathematics; Department Chair


Ph.D., Colorado State University
M.S., Colorado State University
B.S., Northern Arizona University

VPH 122

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 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."

MAT090 - Basic Algebra

This course covers basic concepts of numbers (addition, subtraction, multiplication and division in the integers, rational numbers and real numbers), basic properties of exponents, linear equations in two variables and their applications in problem solving, inequalities, the use of formulas and an introduction to the rectangular coordinate system and graphing. Counts toward full-time student status but is not included in grade point averages. Credit attempted in Basic Algebra does not count toward graduation. Does not count toward a math major or minor. Does not fulfill the math requirement or any graduation requirement. (2 credits)

MAT180 - 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.(3 credits)

MAT211 - Calculus II

A study of transcendental functions, techniques of integration, improper integration, sequences, series, polar coordinates and conic sections.Prerequisite: C- or better in MAT112 or permission of instructor.(4 credits)

MAT325 - Topics in the History of Mathematics

MAT411 - 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)
