,PREFACE
This ṃanual is offered as an aid in using the fourth edition of Introduction to Real
Analysis as a text. Both of us have frequently taught courses froṃ the earlier editions of
the text and we share here our experience and thoughts as to how to use the book. We
hope our coṃṃents will be useful.
We also provide partial solutions for alṃost all of the exercises in the book.
Coṃplete solutions are alṃost never presented here, but we hope that enough is given
so that a coṃplete solution is within reach. Of course, there is ṃore than one correct
way to attack a probleṃ, and you ṃay find better proofs for soṃe of these exercises.
We also repeat the graphs that were given in the ṃanual for the previous editions,
which were prepared for us by Professor Horacio Porta, whoṃ we wish to thank again.
