" However, here on MaplePrimes, there have been hundreds, perhaps thousands, of Questions about third-order BVPs"
well, may be my google search skill is not that advanced. But after going over 2 full google search pages and not seeing an example, I gave up reading PDF files and pages, without seeing just an example. I was not looking for theory, I just wanted to know what the syntax is, that is all.
I was searching for exact syntax of how to specify B.C. for something other that first derivative, which I know. And that is what I could not find. But if you can find a link to such an example, please feel free to post it.
I do not think a user should spend hrs on google and on different forums searching just to find an example of how to do this. This is something that Maple help pages should have under examples section, just like Mathematica does, which contains many usage examples. I find searching Maple help pages very stressful experience each time I use them.
