For fun, I wrote some notes on integration which should provide a good solid introduction to the subject. They are not analysis notes but more of a first introduction to integration.
Any (constructive) comments or suggestions are always welcome.
I just did a quick browse, but this is great, I had read calculus for dummies as my first introduction to the subject and this is of equal if not better quality. Plus its free! thanks a lot, this is great!
At P.5, the symbols for the upper and lower integral at eq. (11) and (13) are just the normal integral sign. Apart from that, I don't see any problems. Good work!
I think this is really good, both as a reference to integration methods and as theory. One thing I could think of is to be careful about [itex]\int _a ^x f(x) dx[/itex], to have a different symbol for the dummy variable.
