Homework Help Overview

The discussion revolves around the topic of interpolation, particularly in the context of preparing for a thermodynamics test. The original poster seeks a quick and easy method to interpolate a point on a chart without having the specific data available.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss various methods of interpolation, with some expressing frustration over the effectiveness of certain equations. There are inquiries about when specific methods may fail and suggestions to visualize data on a Cartesian graph.

Discussion Status

The conversation is ongoing, with participants exploring different approaches to interpolation. Some guidance has been offered regarding the use of algebra to represent data points, but no consensus has been reached on the best method.

Contextual Notes

There is mention of specific resources and equations that may not always yield successful results, indicating potential limitations in the available information or methods. The context of an upcoming test adds urgency to the discussion.

I completely forgot how to do this. I have a thermo test coming up and i will be interpolating a lot of data. What is the fastes/easiest way to interpolate a point on a chart not given?
 
Physics news on Phys.org
yea already looked at that...The first eq. on this site is much easier but someitmes it does not work http://engineering.union.edu/~brunob/mer026/Thermo%20intro%20interpolation.doc

when is that?
 
Think of how the data would appear on a cartesian graph. Represent the two boundary points as a line. You only need simple elementary algebra about equations for a line to find the missing coordinate.
