That would work, but I think it would take too long. If I'm doing the overlays, I want it to be instant -- draw the derivative, then compare it to the actual derivative graph. I'm going to be doing a whole bunch of them in a row, with different students taking turns, and importing and exporting like that would be too long a delay. I can have them draw on one slide, then the next slide shows the actual derivative graph, and just go back and forth between them to compare them.

Got a question about technology? Ask it here. Discussion of hardware, software, TiVos, multi-region DVDs, Windows, Macs, LINUX, hand-helds, iPods, anything tech related. Better than any helpdesk!
Explain Everything is being a bit buggy when I try to import a separate PDF file for each slide. Is there a free way to take multiple PDF files and make them into one file, with each page being one of the original ones?
Goodreader?
it isn't free, but it is a cheap swiss army knife.
I don't need to combine the files on the iPad -- I'm creating them on my MacBook, so if there's a free (or cheap) program I can use to combine them there, then transfer the one big file to the iPad, it would probably be easier.
Preview. That is the way I combine PDFs.
Yeah, Preview will do it. Just open the first file, open the side bar that shows the pages, and drag the next file on top of the last page of the first one. Wash, rinse, repeat.
Really? Cool. Thanks.
Preview is actually a pretty darn powerful PDF editor.
