Suggestion needed : Make an App to show 40 pages from a book

Hey Guys,

I need some suggestions on how to make an App to show some Math formulas on each list item click.

My question is :

Would it be better to include 40 pages of Math formulas as HTML sheets in the App and redirect it on list item click OR include Math formuals as pdf and download it from a remote location and render it using InAppBrowser?

Any suggestions is higly appreciated.

Thanks in advance.
