Review title: absolutely useless
Product review: It starts out okay, good overview of measurable sets and the like. However, it does not even have the essential core theorem to the discipline stating when it is possible to integrate a function! one of the great thing about Lebesgue integration is that a function is integrebale in this sense IF AND ONLY IF the function is measurable. thats the whole point of having measurable functions. there is no if and only if theorem for RS integration. Plus other things, like it talks vaguely about 'randomly choosing a point' but with no precise definition. Things like that.You are better off buying a classic by Halsey Royden or Walter Rudin, or something like that. This book is useless.
