Unit 1: Polynomial Functions
Students will learn the definition and properties of polynomial functions. This unit covers theorems on polynomials, finding zeros of polynomial functions, and graphing polynomial functions. The focus is on understanding the structure, behavior, and applications of polynomials in solving real-world problems.
Unit 2: Exponential and Logarithmic Functions
This unit introduces exponents and logarithms, explaining their rules and relationships. Students explore exponential functions and their graphs, logarithmic functions and their graphs, equations involving exponents and logarithms, and practical applications in growth, decay, and finance.
Unit 3: Solving Inequalities
Students learn to solve inequalities involving absolute values, systems of linear inequalities in two variables, and quadratic inequalities. The unit emphasizes graphical methods and analytical approaches for interpreting and solving inequalities in various contexts.
Unit 4: Coordinate Geometry
This unit focuses on the fundamentals of analytic geometry. Students study the distance between two points, division of a line segment, equations of lines, and properties of parallel and perpendicular lines. Applications include solving geometrical problems using coordinates.
Unit 5: Trigonometric Functions
Students explore basic trigonometric functions, their reciprocals, and simple identities. Real-life applications of trigonometry are included, helping learners understand angles, heights, distances, and periodic phenomena.
Unit 6: Plane Geometry
This unit covers theorems on triangles, special quadrilaterals, properties of circles, and regular polygons. Students apply geometric reasoning and proofs to solve problems, enhancing spatial understanding and logical thinking.
Unit 7: Measurement
Students revise surface areas and volumes of prisms and cylinders, study pyramids, cones, and spheres, explore frustums of pyramids and cones, and calculate surface areas and volumes of composed solids. Emphasis is on practical applications in architecture, engineering, and everyday measurements.
