Nearly constant 0 result from a trig function

Click For Summary

Discussion Overview

The discussion revolves around the use of a trigonometric function, specifically a cosine function with a small amplitude, in the context of interpolation and potential applications. Participants explore the characteristics of the function and its graphical representation, as well as its implications for counting or normalization within a specified interval.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant presents a trigonometric function, suggesting it could be used for interpolation and invites discussion on its applications.
  • Another participant seeks clarification on the term "flat sine function," indicating confusion about its meaning in the context of the discussion.
  • A participant describes the function as having a "nearly flat" appearance over the interval from 0 to 1, emphasizing its small amplitude.
  • There is a proposal to consider whether the function could be utilized for fractional counting from 0 to 1.
  • One participant questions the significance of adding a constant to the sine function and expresses uncertainty about the proposed fractional counting application.
  • A later reply indicates that the original question has been resolved, mentioning an application related to standing waves normalized over the interval from 0 to 1.

Areas of Agreement / Disagreement

The discussion contains multiple viewpoints regarding the interpretation and potential applications of the trigonometric function. Some participants express confusion about terminology and the implications of the function, indicating that consensus has not been reached on its utility.

Contextual Notes

Participants express varying interpretations of the function's characteristics and applications, with some assumptions about its behavior over the specified interval remaining unexamined. The discussion does not resolve the mathematical implications of the proposed applications.

TL;DR
I was fiddling with the amplitude and frequency to find an approximately flat sine function
Interpolating a straight line with a trigonometric function.

In Matlab I ended up with this expression. fplot(@(x)(.0000001*cos(x*2*pi)+10), [0 1])
Would anyone like to discuss what this could be used in?

Sorry, what is a "flat sine function"?

the attached image is hard to read but on the interval 0..1 the function lies with in a very very small amplitude. "nearly flat"

[Edit] I tend to view equations as shapes. Sorry about the "flat" wording

A different plot showing sine vs cosine with a near zero amplitude and normalized 0..1. Could this be used to count from 0 to 1 fractionally?

You just added a constant and a sine function with a small amplitude. Where is the point?

I'm not sure what you mean by that.
 
I needed to plot a curve and needed to normalize 0..1. My question has been answered, Thank you. I was thinking of application to standing wave on a 0..1 (domain or range)
