Description
BIRKHAUSER Functions And Graphs 1991 Edition by I.M. Gelfand E.g. Glagoleva E.E. Shnol
The need for improved mathematics education at the high school and college levels has never been more apparent than in the 1990's. As early as the 1960's I.M. Gelfand and his colleagues in the USSR thought hard about this same question and developed a style for presenting basic mathematics in a clear and simple form that engaged the curiosity and intellectual interest of thousands of high school and college students. These same ideas this same content unchanged by over thirty years of experience and mathematical development are available in the following books to any student who is willing to read to be stimulated and to learn. "Functions and Graphs" provides instruction in transferring formulas and data into geometrical form. Thus drawing graphs is shown to be one way to "see" formulas and functions and to observe the ways in which they change. This skill is fundamental to the study of calculus and other mathematical topics. Teachers of mathematics will find here a fresh understanding of the subject and a valuable path to the training of students in mathematical concepts and skills.
