Interesting links which gave me a BIG giggle right off the bat. Having a couple degrees in Mathematics I figured I would take a peek at what might be out there for electronic texts. What book comes up first in the list?
Differential Equations for Dummies, great woolly jeebus, if you need that book perhaps another course is in order. I KNOW it's a nice review or refresher text if one is rusty but just that title made me laugh because if one struggles at that level, time to look into a different area of study since it is the beginning not the destination of the study of Mathematics.
Nice to see there are a lot more texts out there than when I looked a couple years ago. Thanks for the motivation to look again.
