Ordinary Differential Equations/Help
Examples and Problems[edit | edit source]
We can always use more real world examples, and more example problems both in the text and in the problems and answer section. Even a few help, especially if you have access to mathematica and/or maple and can generate them quickly. I do not and have to solve them by hand, a slow process.
NOTE: Especially need help on the first order linear section. My calc-fu is not up to doing complex integrals of by hand.
NOTE: Especially need more real world examples of both homogenous and nonhomogenous constant coefficient problems.
Checking existing examples[edit | edit source]
Since I do them by hand, there are probably some mistakes among the existing examples. If someone cares to check them and fix any mistakes, it'd be appreciated.
Graphs[edit | edit source]
For the section on graphing- I don't have any good software for generating graphs. If anyone can get me some jpegs of slope fields and isoclines, I can write my explanation to work with your jpegs. Or just write the lesson if you care to.
- I have Mathematica 5.2, I can make some graphs if you give me the equations. Just reply with the equations and I will post them. —The preceding unsigned comment was added by 18.104.22.168 (talk • contribs) 22:23, 30 December 2006 (UTC)
- Just a small note, you'll want to save the graphics as a PNG file. It's a lossless compression format and is best suited for exactly these types of images. I have Mathematica and gnuplot, so I may look into making some graphs. Robert A. Maxwell (talk) 15:00, 29 June 2009 (UTC)
- The matplotlib Python module is freely available, similar to, and nearly as good as Matlab if you are familiar with that.
Write a section[edit | edit source]
Feel free to just go ahead and write a section I haven't gotten to yet. If that would require opening the next chapter that hasn't been broken down yet, I'd be happy to discuss how to do it with you.
