Homework Help Overview

The discussion revolves around understanding the selection of variables in the context of the Cauchy theorem, particularly in relation to a specific expression that needs to be proven. Participants are trying to clarify the reasoning behind the choice of variables h(x) and y(x) in the problem setup.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants express confusion regarding the rationale for selecting specific variables in the proof process. Questions are raised about the purpose of the process and the logic behind defining h(x) as f(x)/g(x) and y(x) as 1/g(x).

Discussion Status

The discussion is ongoing, with participants seeking clarification on the variable selection and the underlying reasoning. Some have noted that the problem is not fully solved, and there is an acknowledgment of the need to understand the process leading to the variable choices.

Contextual Notes

There is a mention of a specific expression that needs to be proven, but details about the expression itself are not provided. Participants are also grappling with the implications of the chosen variables and their roles in the proof.

the key of solving these question is picking the variables
i don't know how they decided to pick those variables?

I can't make heads or tails out of that. You ask "what is the purpose of this process" but I don't see how anyone can tell you that when you haven't said what problem this is supposed to be solving.
 
i need to prove the expression
which is located above the astrix

for that they choose h(x) and y(x)
and make couchy theorem on them
i know that its no completely solved
i know what to do once i build the variables

i can't understand by what logic they chose the h(x)=f(x)/g(x) y(x)=1/g(x)??
 
they are doing some process on the input expression

(which i need to prove) and after that they chose the variables in a certain way
i can't see what the were trying to do in the process
and what lead them to choose this variables??
