Discussion Overview

The discussion revolves around how to plot a parabolic curve for the equation: sigmaY*(1-(L/k)^2/2*(L/k)c^2). Participants explore various software options for plotting, including Excel and Mathematica, while expressing differing opinions on the suitability of these tools.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks guidance on plotting the specified parabolic curve.
  • Another participant suggests using Excel for plotting, questioning the need for more advanced software.
  • Some participants argue against using Excel, stating it is not a good program for this purpose, while acknowledging it can be useful in limited scenarios.
  • There is a mention of Mathematica as a better alternative for plotting, with some participants expressing a preference for it over Excel.
  • One participant humorously notes that while Excel can be used for quick checks, it is not suitable for serious engineering tasks, such as designing a helicopter.

Areas of Agreement / Disagreement

Participants express differing views on the appropriateness of using Excel for plotting, with some advocating for its use in certain situations while others strongly oppose it in favor of more specialized software like Mathematica.

Contextual Notes

Participants do not reach a consensus on the best software for plotting, and the discussion includes varying opinions on the capabilities and limitations of Excel versus Mathematica.

Hi,

Just wondering if anyone could tell me how I would go about plotting the parabolic curve for the equation:

sigmaY*(1-(L/k)^2/2*(L/k)c^2)

Any help most appreciated

What do you mean plotting? Maybe just use Excel? Or do you have access to Mathematica or other math programs?
 
Please do *NOT* use excel. It's not a good program to use.

Well, if you're stranded on a desert island, and all you have is Excel, it's fine for quick plot checks and such. I've done all kinds of weird stuff in Excel, including some DSP development and plots, iterative solutions of non-linear simultaneous equations, etc.

Certainly Mathematica is better for plots, and SPICE is better for circuits, and so on. And given my recent arguments with Office 2007 and Vista, I'm not inclined to be suggesting a Microsoft Office solution, but it is a valid thing to use, after all.

No way I'd design a helicopter with Excel, though... :eek: :biggrin:
