Fantastic – Math Ref Review

update for version 2.4.0 -- the references have been expanded, many toolkits have been added and the user interface has been dramatically upgraded. This is a surprisingly broad compendium of widely used formulas, nicely organized and displayed. The latest revision adds appealing graphics that make what was very good great. A wonderful reference for any college student in math and related fields and graduates searching for reminders. The best dollar I have spent on my iPad; would still be a bargain at $5.
