Kondratyeva L. Questions and Problems in High School Mathematics 1987

Textbook in PDF format This book is intended for all those who wish to enter technical colleges, and its aim is to help students revise the material they studied at school and consolidate their skills in solving the problems and questions they will encounter during the entrance examinations to technical colleges. We hope that the book will also be useful to high-school teachers, who will thereby become acquainted with the requirements of the entrance examinations of technical colleges. All the theoretical questions are followed by brief answers, and the problems are given with detailed solutions and hints. However, we advise the reader to only turn to the answers and solutions after a long and fruitless consideration of the problem. In this book, we use the terminology usually accepted in textbooks. In selecting the questions, we drew upon our long experience of teaching at technical colleges and at schools and have included sample examination papers that contain almost all the questions and problems usually encountered in the entrance examinations.
