Discussion Overview

The discussion centers around the challenge of generating a mathematical function from given coordinates and slopes derived from a graph. Participants explore both manual procedures and software options for function generation, with a focus on accuracy and the nature of the function.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant seeks a manual procedure or software to generate a function from coordinates and slopes, expressing uncertainty about the type of function needed.
  • Another participant suggests considering the type of function (e.g., polynomial, trigonometric, exponential) before attempting to fit a function to the data, noting that fitting without this knowledge may not yield accurate results for other points.
  • A participant mentions that their initial analysis suggests a linear relationship (y=mx), but they are looking for a more accurate function due to slight deviations from a straight line, indicating a need for further refinement.
  • One participant points out that Excel has a curve fitting function that could be useful for this task.

Areas of Agreement / Disagreement

Participants express varying opinions on the type of function that may be appropriate, and there is no consensus on a specific method or software for generating the function. The discussion remains unresolved regarding the best approach to achieve an accurate function.

Contextual Notes

Participants have not established the assumptions regarding the nature of the function or the specific mathematical processes required for accurate function generation. The discussion also lacks clarity on the limitations of the suggested software options.

hi fellas, i have been given a graph from which i can extract the coordinates and the slopes but all i need is to generate the function this graph represents. can you suggest me any manual procedure to do this mathematically or do i have to use software to generate polynomial functions?
if there is any useful software to generate functions from co ordinates please let me know

Do you have any ideas, suspicions etc as to what sort of function it is - polynomial, trigonometric, exponential...
Without that one could work out a function that fits the values and slopes but it wouldn't necessarily produce correct values for other points.
 
i got the curve to be sort of a straight line. I might have worked out with it to get a y=mx curve, but i m looking for a more accurate function because my straight line is slightly deviating from its path, not exponential though..actually i need to know if there is any mathematical manual process to get the accurate function or if you can suggest me a software which does it?
 
Excel has a curve fitting function.
