What Should I Study Before Real Analysis?

Studying for math


Real analysis is a branch of mathematics that deals with the study of real numbers, sequences, and functions. It is considered to be one of the most important branches of mathematics due to its wide range of applications in various fields, including physics, engineering, and economics. If you are interested in studying real analysis, there are a few things you should consider studying before diving into the material.


What is real analysis?

Real analysis is the study of continuous functions and structures on real numbers. Its roots go back to Calculus which deals with the study of derivatives and integrals. Real analysis extends concepts from calculus to more general settings, including the study of functions in multiple dimensions and differentiability in discontinuous functions.

What should I study before real analysis?

Before delving into real analysis, it is recommended that you have a solid foundation in mathematical concepts like proofs and basic set theory. Understanding logic, methods of proof, set operations, relations, functions, and cardinality are important concepts to understand for many fields of mathematics. A great resource for learning these concepts is a free online text called Book of Proof.

What are some other topics I should study?

Other important topics to study before real analysis include calculus, linear algebra, and topology. Calculus teaches students the basics of derivatives and integrals, while linear algebra focuses on matrix algebra and vector spaces. Topology is the study of the shape of spaces, including the properties that are preserved under continuous transformations.

Is programming important in real analysis?

Programming is not a fundamental skill for studying real analysis, but it can be a helpful skill to have. Numerical analysis is a branch of mathematics that deals with the numerical approximation of solutions and real analysis problems, and programming can be extremely helpful in that area. Python, MATLAB, and Julia are popular programming languages for numerical analysis and real analysis.

What Skills Should You Have?

If you want to study real analysis, you should have a strong foundation in calculus and linear algebra. You should also have a solid grasp of mathematical proof techniques, including direct proofs, proof by contradiction, and mathematical induction. Good visualization skills are also important, as real analysis often deals with studying functions in multiple dimensions.
