The discussion revolves around a precalculus trigonometry problem related to arc length, specifically focusing on a question from a released math exam. Participants are examining the interpretation of the term 'total perimeter' in the context of a wiper's motion.
Some participants have provided insights into the interpretation of the problem, suggesting that the total perimeter involves considering the entire path traced by the wiper. There is an acknowledgment of a missed detail in the problem statement, indicating a productive exploration of the topic.
Participants note a potential misunderstanding regarding the problem's wording, particularly the term 'total perimeter,' which may affect their calculations and interpretations.
I think 'total perimeter' here means you go entirely around the area which is swept out by the wiper.A123 said:Homework Statement
