This book on "Fundamental Calculus" has been specially written to meet the requirements of the B.G first semester students of all Indian universities. The subject matter has been discussed in such a simple way so that the students will find no difficulty to understand it. The proofs of various theorems and examples have been given with minute details. Each unit of this book contains complete theory and fairly large number of solved examples. Although, the authors have tried their best in the formulation of the subject matter very nicely, but that can be further improved by the suggestions received from its readers.
