Название: Journey into mathematics: An introduction to proofs
Автор: Rotman J.
This 3-part treatment begins with the mechanics of writing proofs, proceeds to considerations of the area and circumference of circles, and concludes with examinations of complex numbers and their application, via De Moivre's theorem, to real numbers. "I recommend this as a textbook or supplemental textbook." — Brian Rogers, The Mathematical Association of America. 1998 edition. >
