I have searched the mainstream books thomas calculus, steward and lots other like apostols,rudin etc. I was given two books in my college called analysis and applications but it is in greek written by an old local proffessor . It is 1600 pages total 2 volumes.. However the second book has these topics. Arithmetical Methods Improper integrals (30 pages theory + 75 pages excercises) -first,second,third type -convergence tests -parametrical improper integrals -gamma and betta functions Laplace transform Series of functions Two variable functions Double integrals Multiple variable functions However i didnt find any book that has 75 pages with excersices for improper integrals only! Each chapter has tons of excercises.The problem is that most of them dont have solutions. But couldnt find another book. Searched analysis books but they didnt even mentioned these stuff.Searched calculus and advanced calculus but no luck.. Is there any reccomendation that has lots of excercises with solutions ?
