2.3 Criterion B: Mathematical Communication

Instances of achieving marks on this criterion is explained in more detail below:

1. 4 marks (Excellent):
   1. Mathematical communication is consistently relevant, appropriate, and precise throughout the exploration.
   2. All variables are clearly defined, and standard mathematical notation is used correctly and consistently.
   3. Calculations and derivations are presented logically, step-by-step, and are easy to follow.
   4. Visuals are fully labeled and integrated, significantly enhancing the mathematical narrative.
2. 2 marks (Acceptable):
   1. Mathematical communication is generally relevant but may lack consistency or full appropriateness in places.
   2. Some variables might be undefined, or there may be minor inconsistencies in notation (e.g., occasional use of calculator shorthand) or rounding.
   3. Calculations are mostly clear but might occasionally skip steps, making them harder to follow.
   4. Visuals are present but may have minor labelling omissions or lack full integration.
