The student used correct mathematical notation, symbols, and terminology consistently and correctly, except for the uniformity of decimal places. Key terms and variables are defined and explained when first introduced, and the main concepts are described in the introduction. The additional terms are also defined in detail in appropriate places, and multiple forms of mathematical representation are used effectively. However, the degree of accuracy is not stated for rounded values, and the graphs, tables, and diagrams are not consistently labeled at the bottom. Overall, the student has demonstrated a good understanding of mathematical concepts and effective communication of their exploration.
