The student uses correct mathematical notation, symbols, and terminology consistently throughout the IA, demonstrating a clear understanding of the concepts involved. Key terms and variables are defined and explained appropriately when first introduced, and additional terms are also defined in detail at relevant points in the exploration. The student effectively employs multiple forms of mathematical representation, such as formulae, diagrams, and graphs, to enhance understanding. However, there are areas for improvement; specifically, the student should include clearer references to computer notation, explicitly describe main mathematical concepts in the introduction, and explain all mathematical calculations and data presentations more thoroughly. Overall, the student's work exhibits a solid grasp of mathematical principles, though some clarifications would strengthen the analysis.
