HP Functions

You are totally correct as respects posting and publishing on forums and print media. Publishing on iBooks, Kindle, etc. requires a different approach and pdf is one of the easy paths. Because of the flexibility of the medium, concepts like page numbers, type sizes and even choice of font are not as would be the case in print. Users can select bigger-smaller, often in a font of their choice and the document renumbers all the pages (although the numbers may only be displayed when searching in some cases). The fixed-layout ePub seems not to be the way of the future for a long list of reasons.

I didn't look at the pdf sample, I just bought the book on Amazon and wasn't overly concerned about the inconsistencies you mentioned, mostly because the Prime is not the most consistent of systems itself, either in function or documentation. (e.g. the difference between eigenvects() and EIGENVV() output has me baffled)

As I wrote in my post, I'm a bit rusty on the latest details of e-publishing and certainly a word processor like MS Word may not be the best choice for formulae, but in terms of publishing something useful, the "Functions" author has delivered excellent value for the $0.99 the book cost me. The "cut and paste" motif is retro enough to be almost charming and having the example actually "cut" from the display is an advantage for new users, I think.

Thanks for the advice on the apple support for LaTeX, I'll look into it.
(Now XyWrite, that was a real word processor!)

UPDATE:
Thanks to the good advice from Han, I followed the link suggested and ultimately found an iPad App that accepts handwritten formulae and poops out LaTeX or MathML for inclusion in an iBook among other things. The app is "MyScript MathPad" and is "free" with in app purchase $4.99 for the permanent unlock of the conversions mentioned above.

Wahoo! No excuse not to have pretty math . . ..
