Calculus: One and Several Variables by Saturnino L. Salas, Garret J. Etgen, and Einar Hille is a textbook that provides a progressive approach to exercises but suffers from overly concise explanations filled with dense jargon. While it offers a satisfactory treatment of multivariate concepts and proves most theorems, it lacks accessibility for students, particularly in its late introduction of fundamental concepts like the least upper bound property of R. For undergraduates pursuing theoretical physics, particularly in quantum field theory (QFT), this text is insufficient, necessitating further study beyond its content.
PREREQUISITESThis discussion is beneficial for undergraduate students in mathematics and theoretical physics, particularly those seeking foundational calculus knowledge and guidance on suitable texts for advanced studies in quantum field theory.
Salas, Hille, Etgen's Calculus is okay but if you want to do QFT, you pretty much need to go beyond this text. I have used this book for my elementary calculus classes only.shinobi20 said:Hi micromass, I just want to ask if Calculus by Salas is enough for theoretical physics undergraduates? I am curious because I want to do research in QFT in grad school and I'm thinking if my investment for Salas is enough.
