Terry DEPARTMENT OF MATHEMATICS Jack Atkins, Paul Hulsh, E. C. Murphy*, L. E. Rich, M. L. Stevenson G. Alexander, W. Z. Terry A student pursuing a major in mathematics should complete Mathematics 4, 10, 7, 8, 9, and Physics 4, 5, 6. 1. Intermediate Algebra. A course designed for the general student as well as for the science student. It deals with the fundamental algebraic operations, special products and factoring, fractions, linear equations in one, two and three unknowns, graphs, exponents, radicals, quadratic equations, logarithms, and variations. Prerequisites: One year of high school algebra or its equivalent. Five quarter hours. Autumn, Winter, Spring. Atkins, Stevensen lc. Intermediate Algebra. Mathematics lc and Id may be substituted for the one quarter course of Mathematics 1. These courses are designed to meet the needs of those students who need intermediate Algebra, but whose background in Mathematics is such that they cannot successfully complete, intermediate Algebra in one quarter. Prerequisite: One year of high school Algebra or its equivalent. Five quarter hours. Autumn, Winter, Spring. Atkins, Stevenson * On Leave of Absence
