# I hate my DE text

#### Plastic Photon

My DE class (for engineers) requires that the text be printed (for free at university!!!), and not that saving money is bad, but I wan't a book that can give me the same information for cheap.

I am thinking about these dover books that come $14-$20. Any suggestions?

You couldn't go amiss with the Schaum's Outline entitled, "Modern Introductory Differential Equations". It's in that price range. The great thing about any Schaum's Outline is the massive amount of solved problems and supplementary exercises with answers.
