why you don't translate them to English or German ...get an autotranslator...it will help us.
I found your collection good..
I am writing or collecting interesting integrals
and techiques for solving them. All from formulas, to special functions and so forth.
It is not intended to be an exhaustive list asGradshteyn and Ryzhik, but more a collection of puzzles
and interesting ideas.
http://folk.ntnu.no/oistes/Diverse/Problems.pdf <- The problems I have collected so far
http://folk.ntnu.no/oistes/Diverse/DelIII.pdf <- The part about advanced integration techniques
I know the language is a barrier, but hopefully most of it can be understood nevertheless. An integral is still an integral.
Now I do not come here to brag or show off, but I need your help to get ridd of the boring problems
and more so get even more fun and interesting integrals. =)
So if you spot any boring problem, or if you know a very nice integral I have yet to include please
write it here!
