The student has consistently and correctly used mathematical notation, symbols, and terminology throughout the work. Computer notation is present only when it is software-generated, with clear indication. Key terms and variables were appropriately defined and explained when first introduced, and the main concepts were described in the introduction, such as the utilized mathematical methods. Multiple forms of mathematical representation, including formulae, diagrams, tables, charts, graphs, and models, are present and used appropriately. Additionally, all mathematical calculations were explained, and any data presentation was described. However, the degree of accuracy was not stated for rounded values, and the results were rounded only at the end of the calculations thread. The student also used a deductive method and provided logical proofs where appropriate, and the graphs, tables, and diagrams were labeled at the bottom.
