The student consistently and correctly uses correct mathematical notation, symbols, and terminology. Key terms/variables are defined and explained when first introduced, but linearization procedures are not explained and should be made clear and referenced. The main concepts are described in the introduction, and additional terms are defined in detail in appropriate places. Multiple forms of mathematical representation are present but used only if appropriate. All mathematical calculations are explained and any data presentation is described. The student used a deductive method and set out logical proofs where appropriate, however, the graphs, tables, and diagrams are not labeled and often crooked.
