Homework Help Overview
The problem involves determining the dimensional correctness of the equation y=2 cm * cos(k*x), where k=2 m^-1. Participants are questioning the dimensions of the variables involved, particularly what x and y represent in a physical context.
Discussion Character
- Exploratory, Assumption checking, Conceptual clarification
Approaches and Questions Raised
- Participants are exploring the dimensions of y and questioning the meaning of x. There is discussion about whether x could represent an angle or arc length, and how k relates to these dimensions.
Discussion Status
The discussion is ongoing, with participants raising questions about the definitions and dimensions of the variables. Some guidance is being offered regarding the nature of the variables, but no consensus has been reached on their specific meanings.
Contextual Notes
There is a lack of information regarding the definitions of x and y, which is central to understanding the dimensional correctness of the equation. Participants are also considering the implications of using radians in the context of the cosine function.
