This is a first course in Calculus. It is described very well in the Authors own words..."The approach to the subject is elementary, but it is hoped that a student proceeding to a mathematical career will not have to unlearn anything when he enters the wider field."

Practically speaking; I would say that the authors wishes both for the above and for his other wish to satisfy his compassion for "Students overladen with satchels full of expensive and weighty tomes, which for some strange reason appear to be growing larger with the years"; has been satisfied: At least as far as this 'Practical Calculus' is concerned.
In the many years that I have had it, and used it as a quick reference; for it has many practical problems of a general nature concerning particular methods of differentiation and Integration, along with their solutions clearly developed step by step used as a method of instruction; it has proved it's value, and the truth of the old expression... "Good things come in small packages!"

This Tome comes in a package about 5 and 1/8th inches (Wide) by 7 and a 1/2 inches (long) by 7/8th inches (thick).....
An excellent carry anywhere reference for Engineers of any Discipline!
