OK. That was one big file you have there. It's 1.3 mb (232 pages!). But, Note Taker HD had ZERO trouble loading it in. None.
I went to the web page you posted above and I opened the PDF file on my iPad (just selected the link and Safari opened the PDF in the browser). In the upper right hand corner, there was an "Open In…" button. I pressed it and then selected "Open in Note Taker HD." The app opened and I selected the "Create Page" button (as there is another option to make the PDF a background image - but that's not what you want).
Took about 30 seconds for the app to load the 232 (!) pages. I then made the annotations to the file as you see in the linked pictures. I didn't write on many pages but I did scroll all the way to the end of the file. Not a hiccup from NT-HD.
Oh, and one other thing. I initially put the PDF into my Dropbox file (via my computer). On the iPad, I opened my Dropbox icon, selected the PDF and then selected "Open in NT-HD." Took a bit of download time, but, really no problem there. So, if you get stuff into Dropbox, even big files like this one, there's no trouble getting it onto the iPad.
Then, I went to get it off the iPad. And, I discovered something new (or something I didn't think about before). No Dropbox (or any cloud) support right now with Note Taker HD. Huh. But then, I've never done anything with my notes in the app before except study from them on the iPad. Hopefully, it's one of the things the developer is working on.
Anyway, you can e-mail the file, so that's good. Takes a bit for the file to go through, but it went with no issues (I have gmail … worked fine). When I opened the file on my desktop (running Windows 7 Professional), I was able to see my annotations just fine, both in Google's web viewer (Google Docs) online and in Adobe Reader (after saving the document to my desktop). So, it works there.
I also think there is a way to just selectively pick various pages to e-mail. I didn't look too closely, but it looks like it. If I'm wrong, sorry 'bout that…
You can also access the file via iTunes (from within the Apps tab when your iPad is hooked up). Just scroll to the bottom and you'll see where NT-HD has a file-sharing section. It's a little hard to understand how to do it, but I
was able to get the file out via iTunes. There is a very extensive Help section in the app, so if I can follow it …
I've got some pictures linked here:

So, there you go. After looking at your workbook, I can only wish you luck, both in DOING the maths and in working it with the iPad. I don't know if you'll be happy writing in such a small area on the iPad (the stylii that work with the iPad aren't as precise as a well-sharpened pencil) but - if you want to use your iPad to annotate on this worksheet, or others like it - IMNSHO, Note Taker HD is the app to do it with.
Good luck.
