Unit 1: Further on Relation and Functions
In this unit, students explore additional types of functions, their classification, composition, and inverses, as well as graphing techniques for different function types.
Unit 2: Rational Expressions and Rational Functions
In this unit, students learn to simplify rational expressions, solve rational equations, and interpret graphs of rational functions.
Unit 3: Coordinate Geometry
In this unit, students study the properties of straight lines and conic sections, applying equations to solve geometric problems.
Unit 4: Mathematical Reasoning
In this unit, students are introduced to formal logic, the structure of arguments, and how to assess the validity of different forms of reasoning.
Unit 5: Statistics and Probability
In this unit, students practice organizing and analyzing data using statistical methods and apply probability concepts to predict events.
Unit 6: Matrices and Determinants
In this unit, students learn about matrix operations, determinant properties, inverse matrices, and solving systems of equations using Cramer’s rule.
Unit 7: The Set of Complex Numbers
In this unit, students gain an understanding of complex numbers, their operations, modulus, conjugates, and polar representation using Argand diagrams.
Unit 8: Vectors and Transformation of the Plane (For Natural Science Students)
In this unit, students review vector concepts, scalar products, applications of vectors, and transformations of the plane.
Unit 9: Further on Trigonometric Functions (For Natural Science Students)
In this unit, students explore secant, cosecant, and cotangent functions, their inverses, graphs, and real-world applications.
Unit 10: Introduction to Linear Programming (For Social Science Students)
In this unit, students study graphical solutions to linear inequalities, optimization techniques, and real-life uses of linear programming.
Unit 11: Mathematical Applications in Business (For Social Science Students)
In this unit, students apply mathematical concepts to business situations such as compound interest, depreciation, investments, taxation, and financial planning.
