What I hate about math textbooks

[CallTheFBI]

What I really hate about math textbooks is that at the beginning of every section they have examples. But they only show you like 4 or 5 examples (if that). Sometimes this is enough, the examples really do help you get through the entire section. A lot of the time though you get to a problem in the section and you are like: "whhaaaaattt?" then you go to look at the examples and they are NOTHING like the problem you are trying to solve. Eh, I guess that is one reason why it helps to have more than one textbook.

Buy the teacher's edition off eBay and call it a night.

It's rare that a math book will toss you something that's totally off the wall at you. Usually it's some form of an example or an equation in the section taken to the extreme and beyond. Although having a few references books couldn't hurt, schum's outline rocked for this purpose.

Well my textbook has this really weird section called: Techniques of Integration: Miscellaneous Substitutions. It has this really freaking weird theorem involving substitutions for sinx and cosx that just totally does not seem to work for a couple problems. I've been searching the web and no other site has anything even close to the method this book describes.

What kind of substitutions?
