The student did not use correct mathematical notation, symbols, and terminology consistently and appropriately, as there were multiple equal signs in a single line of equations. The use of computer notation was not applicable in this exploration. The main concepts were briefly described in the introduction, but a more in-depth explanation would have been beneficial. Additionally, the degree of accuracy for rounded values was not stated, and the labels of the graphs, tables, and diagrams were not placed at the bottom as required. However, key terms/variables were defined and explained when first introduced, additional terms were defined in detail, and all mathematical calculations were explained with data presentation described. The student also used a deductive method and set out logical proofs where appropriate, and rounded results only at the end of the calculations thread.
