Terry General Prerequisites: Each course in elementary mathematics requires a knowledge of mathematical principles and an understanding and a working knowledge of the content of courses previously studied. The student's success in future mathematics courses is dependent upon this knowledge and understanding. For this reason, it is required that the student complete all prerequisite courses in mathematics with a C grade or better. Whenever a lower grade in a mathematics course is received, or the substance of the course is forgotten, the student should repeat the particular course. A mathematics placement test is required, prior to registration, of all students who have not completed the specified prerequisite courses within the past two years. Exceptions to this requirement are: 1. Those students who have completed equivalent courses within the past two years with a C grade or better at an accredited college. 2. By approval of the head of the mathematics department. This regulation is designed primarily for the benefit of the student and for the efficiency of the teaching staff. When the student is registered in the proper course, he has a reasonable chance for successotherwise, he almost invariably runs into failure. Arrangement to take the prescribed placement test should be made at the Personnel Office, Room 139 in Building No. 1 While the department aims to set up ways and means to see that students are registered in the proper mathematics courses, the primary responsibility rests with the student. COURSES OF INSTRUCTION Mathematics 1. Intermediate Algebra. A course designed for the general student as well as for the science student. It deals with the fundamental laws and algebraic operations, signed numbers, the language of algebra, simple equations, formulas, statement problems, special 123 products, factoring, fractions, graphic equations, exponents, radicals, quadratic equations in one unknown, and selected topics. Prerequisites: Mathematics 53, or satisfactory performance on a placement test. 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 trigonometry 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 and plane geometry or satisfactory performance on a placement test in intermediate algebra. 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. Prerequisites: Mathematics or its equivalent and plane geometry. Credits will not be given for both Mathematics 3 and 3a. Three quarter hours. Spring. (May not be given 1957-58.) Staff 4. College Algebra. For mathematics, science and engineering majors. Deals with quadratics, ration and proportion, binominal theorem, progressions, mathematical induction, inequalities, complex numbers, theory of equations, logarithms, determinants, and selected topics. Prerequisite: Mathematics 1 or satisfactory performance on a placement test on intermediate algebra. Five quarter hours. Autumn, Winter, Spring. Staff 5. Analytic Geometry. A course in plane analysis geometry which, together with Mathematics 6, constitutes a more thorough and complete course in analytic geometry which is designed for those students who desire a stronger background of mathematics as a prerequisite to the calculus. This course deals with plane and analytic geometry, cartesian, and polar coordinates, lines, curves and equations, conic sections, and transformation of coordinates. Prerequisites: Mathematics 3 and 4. Five quarter hours. Winter. (May not be given 1957-58.) Staff 6. Analytic Geometry. A continuation of Mathematics 5. It deals with plane and solid analytic geometry, polar coordinates, higher plane curves, tangents, normals, graphs, functions, empirical equations, three demensional coordinates, surfaces and curves in space. Prerequisites: Mathematics 5 and 2 (or may be taken with Mathematics 2 concurrently). Five quarter hours. Spring. (May not be given 1957-58.) Staff
