Terry General Prerequisites: Each course in college mathematics requires a knowledge of mathematical principles and an understanding of the content of courses previously studied. It is important that the student complete all prerequisite courses in mathematics. Whenever a low grade in a mathematics course is received or the substance of the course forgotten, the student should repeat the particular course. To determine a student's mathematical background and his possibility of success in further mathematics courses, a special examination may be required by the Department. Departmental Major: A student pursuing a major in Mathematics will be required to complete the "Graduation Requirements" as specified on pages 30 33 and should include Mathematics 4, 10, 7, 8, 9, and Physics 4, 5, 6. Teaching Major: It is recommended that a student pursuing a teaching major in Mathematics complete the courses specified for the "Departmental Major" and consult the Department of Education for additional courses prescribed by that department. 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. Prerequisite: One year of high school algebra or its equivalent. Five quarter hours. Autumn, Winter, Spring. Staff 2. Solid Geometry. A course dealing with lines, planes, dihedral and polyhedral angles, prisms, cylinders, pyramids, cones, spheres, spherical polygons, and general polyhedrons. Prerequisite: Plane Geometry. Three quarter hours. Winter, Spring. Atkins 3. Trigonometry. Plane and spherical trigonmetry designed primarily for mathematics, science, and engineering majors. It deals with the natural functions and their graphs, identities, functions of the sum of two angles and related formulas, logarithms, solutions of triangles, complex numbers, inverse functions, hyperbolic functions, equations, spherical triangles. Prerequisites: Mathematics 1 or its equivalent and plane geometry. Five quarter hours. Winter, Spring. Staff 3a. Trigonometry. Plane trigonometry designed for general students, some engineers, and other non-mathematics majors. It includes the natural functions, their line values and graphs, identities, functions of the sum of two angles and related formulas, logarithms, solution of triangles and inverse functions.
