About this book :-
"Elementary Calculus: An Approach Using Infinitesimals" by H. Jerome Keisler introduces "calculus" through the intuitive use of "infinitesimals" and "hyperreal numbers". This approach allows students to understand fundamental concepts like "derivatives" and "integration" directly, reflecting the historical ideas behind calculus while maintaining rigorous mathematical validity. The book provides a clear, accessible foundation for beginners and those exploring alternative methods of learning calculus. Keisler’s text begins with the basics of continuity, derivatives, and integrals using infinitesimals, making abstract concepts more tangible. It gradually introduces the traditional "limit" definitions, and extends the curriculum to include series, transcendental functions, vectors, partial derivatives, and multiple integrals. By combining intuitive reasoning with standard methods, the book ensures that learners gain both conceptual understanding and practical problem-solving skills. Ideal for undergraduates, independent learners, and instructors, the text encourages exploration and curiosity in calculus. Its unique use of infinitesimals helps students build confidence while reinforcing rigorous thinking. "Elementary Calculus: An Approach Using Infinitesimals" equips readers with the tools to master fundamental calculus topics, bridging the gap between intuitive understanding and formal mathematical analysis, and providing a strong foundation for further studies in mathematics, physics, and engineering.
