This course is an introductory course for grade 9 students and aims to provide a rigorous study of the fundamental concepts of functions leading to advance concepts of special functions. It assumes students’ thorough understanding of basic algebraic concepts including graphs and equations. It continues the study of types of functions, analysis of graphs, and properties of functions using ICT tools and manipulative devices, and viewing functions as a way to model real-life data. The course ends with a discussion of trigonometry and trigonometric function and their applications.
