Applicability of "Intro To Algebra" and "Intro to Real Analysis" to Physics Well, due to timetable complications I'm having to search for courses that aren't apart of my graduation requirements so I'm thinking about taking some math courses. Which one of these courses do you think is more applicable to physics? Have you taken either of these and did you enjoy them? Thoughts on more or less what these courses will be like? Intro To Algebra: Definitions and examples of groups, rings, fields, and integral domains; rational numbers, real numbers, and complex numbers; polynomials and their factorization; permutations. Additional topics chosen from Boolean algebras and lattices, and transfinite arithmetic. Intro To Real Analysis: Axiomatic and metric properties of the real numbers. Sequences and limits. Completeness, compactness, Bolzano-Weierstrass and Heine-Borel theorems. Infinite series. Continuous and uniformly continuous functions. Thanks for your help!
