The student demonstrates a consistent and correct use of mathematical notation, symbols, and terminology throughout the work. Key terms and variables are appropriately defined and explained when first introduced. The main concepts are effectively described in the Theoretical Background. Additionally, the student provides detailed definitions of additional terms in appropriate places and utilizes multiple forms of mathematical representation, such as formulae, tables, and diagrams, when necessary. Furthermore, all mathematical calculations are explained, and any data presentation is described, contributing to a deductive method and logical proofs where appropriate. However, there is a need for improvement in labeling the graphs, tables, and diagrams at the bottom instead of the top.
