Question

Mathematics

I can't decide between Zorich and Rudin. What do you advise ??
Fichtelholtz not to offer

Answer 1

Higher mathematics for beginner physicists and technicians. Zeldovich Ya.B., Yaglom I.M.
The book is an introduction to mathematical analysis. Along with a presentation of the principles of analytic geometry and mathematical analysis (differential and integral calculus), the book contains the concepts of power and trigonometric series and the simplest differential equations, and also touches on a number of sections and topics from physics (mechanics and theory of oscillations, theory of electrical circuits, radioactive decay , lasers, etc.)
The book is intended for readers interested in natural-science applications of higher mathematics, university professors and technical colleges, as well as future physicists and engineers.

Answer 2

Both books require a good level of preparation from the reader.
If there is none, it is better not to take them.
And they don't replace each other. So there is no such choice - one or the other.
