DEPARTMENT OF MATHEMATICS AT UNIVERSITY OF GHANA

COURSE DESCRIPTIONS AND PREREQUISITES
Prerequisite for 100 LEVEL: SHS (or equivalent) grade B in elective mathematics.
LEVEL 100
MATH 101: General Mathematics I (Non-Mathematics students)
Indices and Logarithms. Equations and inequalities. Functions and graphs. Arrangements and
selections. Binomial theorem. Limits, differentiation and integration.
MATH 121: Algebra and Trigonometry
This course is a precalculus course aiming to develop the students ability to think logically, use
sound mathematical reasoning and understand the geometry in algebra. It examines: logic and
concept of mathematical proof; sequences and series; elementary set theory; the algebra of surds,
indices and logarithms; the concept of a function, identifying domain and range and injective and
surjective functions; trigonometric functions, their inverses, their graphs, circular measure and
trigonometric identities.
MATH 123: Vectors and Geometry
Vectors may be used very neatly to prove several theorems of geometry. This course is about
applying vector operations and the method of mathematical proof (of MATH 121) to geometric
problems. The areas of study include: vector operations with geometric examples; components of
a vector and the scalar product of vectors. Coordinate geometry in the plane including normal
vector to a line, angle between intersecting lines, reflection in a line, angle bisectors and the
equation of a circle, the tangent and the normal at a point.
MATH 122: Calculus I
Calculus is the mathematics of change and motion. This course develops the mathematics of
change and the course MATH 124 will explicitly develop the mathematics of motion. In this
course we address: limits and continuity of real valued functions of a single real variable; the
derivative as a limit, algebraic rules of differentiation, implicit differentiation and the derivative
of a function in parametric form; integration and the solution to first order differential equations.
MATH 124: Mechanics
In this course we deal with the calculus involved with motion. Kinematics deals with the study of
motion without reference to the cause of the motion. So we first study kinematics and then we add
the ingredient of the cause of the motion, force. So, we study statics, where the sum of the forces
on the body is zero and we study dynamics, where the sum of the forces on the body is no longer
zero.
