Homework Help Overview
The discussion revolves around the computation of the subdifferential of a non-convex function defined as f(x) = x^2 sin(1/x) for x ≠ 0 and f(0) = 0. The original poster is seeking guidance on how to approach this problem, particularly at the point x = 0.
Discussion Character
- Exploratory, Conceptual clarification, Assumption checking
Approaches and Questions Raised
- Participants discuss the definition of subdifferentiation and question its applicability to the given non-convex function. The original poster expresses uncertainty about the process and whether a direct formula exists. Others inquire about the convexity of the function and its implications for finding the subdifferential at zero.
Discussion Status
The discussion is ongoing, with participants sharing definitions and exploring the concept of subdifferentiation. Some guidance has been provided regarding the nature of convexity and its relevance to the problem, but no consensus has been reached on how to compute the subdifferential for the specific function in question.
Contextual Notes
Participants note that the function is not convex, which raises questions about the feasibility of finding the subdifferential at the origin. The original poster references an example of a convex function to contrast with their own, indicating a potential misunderstanding of the concepts involved.
