Limit of Newton's Law of Cooling....2

Click For Summary

Discussion Overview

The discussion centers around the mathematical analysis of Newton's Law of Cooling, specifically focusing on finding the limit of the function u(t) as t approaches 0 from the right. Participants are also interested in the graphical representation of this law.

Discussion Character

  • Homework-related, Mathematical reasoning, Debate/contested

Main Points Raised

  • One participant presents the function u(t) = (u_0 - T)e^(kt) + T and asks for hints on finding the limit as t approaches 0, suggesting the limit is u_0.
  • Another participant echoes the same question about finding the limit and inquires about the graph of the Law of Cooling.
  • A third participant expresses frustration with the lack of clarity in the responses and requests a more detailed explanation of the problem, indicating that they want to understand the process rather than just the answer.
  • A fourth participant suggests that providing a screenshot of the entire problem would help clarify the conditions needed for k, implying that important details may be missing from the discussion.

Areas of Agreement / Disagreement

There appears to be a lack of consensus on how to approach the problem, with some participants seeking clarification and others expressing dissatisfaction with the responses provided. The discussion remains unresolved regarding the best way to assist the original poster.

Contextual Notes

Participants note that some details of the problem are left out, which may affect the understanding of the limit and the conditions for k.

Given u(t) = (u_0 - T)e^(kt) + T, find the limit of u(t) as t tends to 0 from the right side.

The answer is u_0. How is the answer found? Seeking a hint or two.
Can this Law of Cooling be graphed? If so, what does the graph look like?

Problem 1.5.75.b.
Some details left out.
Suggest you post a screenshot of the entire problem instead of making helpers guess the condition for k.
 
Look at 75 parts (a) and (b). You are not helping by telling me to go back to the question. I want to learn how this is done.

Do us all a favor and post a screenshot of your problem so we don't have to task our imagination with sloppy typing.
