The student consistently and correctly used mathematical notation, symbols, and terminology throughout the work. Key terms and variables were appropriately defined and explained when first introduced, and the main concepts were described in the introduction. Multiple forms of mathematical representation, such as formulae, diagrams, tables, charts, graphs, and models, were present and used appropriately. However, the student did not explain all mathematical calculations and data presentations, and the degree of accuracy for rounded values was not stated. Despite this, the student used a deductive method and provided logical proofs where appropriate, and the graphs, tables, and diagrams were labeled at the bottom.
