The student uses correct mathematical notation, symbols, and terminology consistently throughout the IA, clearly defining and formatting equations related to pursuit curves. Key terms and variables are introduced with clear definitions, and the main concepts are well described in the introduction, highlighting the relevance of the topic. The student effectively incorporates multiple forms of mathematical representation, including diagrams and graphs, which aid in illustrating the chase dynamics. However, the student does not specify the degree of accuracy for rounded values, which could enhance clarity. Overall, the student demonstrates a logical and structured approach to the investigation, with all calculations explained and results rounded appropriately at the end.
