This book presents first-year calculus roughly in the order in which it
was first discovered. The first two chapters show how the ancient
calculations of practical problems led to infinite series, differential
and integral calculus and to differential equations. The establishment
of mathematical rigour for these subjects in the 19th century for one
and several variables is treated in chapters III and IV. Many quotations
are included to give the flavor of the history. The text is complemented
by a large number of examples, calculations and mathematical pictures
and will provide stimulating and enjoyable reading for students,
teachers, as well as researchers.
