A text book of Calculus

Calculus has long been recognized as a powerful tool in the study of basic and applied sciences, particularly Applied Physics. With this in mind, the present book has been prepared according to the revised syllabus of Veer Bahadur Singh Purvanchal University, specifically for undergraduate students of B.A./B.Sc. Part I Mathematics. The material is presented in a systematic, complete, and self-contained manner to support effective learning. Every effort has been made to ensure clarity and accuracy, though minor errors may remain. The authors welcome constructive suggestions from teachers and students for further improvement. We gratefully acknowledge the support and cooperation of Vandana Prakashan in bringing out this work. It is our hope that this book will serve as a reliable guide for students beginning their study of Calculus.
