# Handwritten Notes of Real Analysis by Asim Marwat Real analysis is a branch of mathematics that analyses how real numbers, sequences and series, and real functions behave. It focuses on real numbers and frequently extends the real line by including positive and negative infinity. Real analysis investigates a number of the properties of real-valued sequences and functions, including convergence, limits, continuity, smoothness, differentiability, and integrability.

The field of mathematics known as “real analysis” was created to describe the study of real numbers and functions as well as to explore fundamental ideas like limits and continuity. These concepts form the foundation of calculus and its applications. Real analysis is becoming a crucial tool in a wide range of applications.

These are basic notes useful in MSc or BS mathematics for real analysis. We appreciate Asim Marwat for making these notes available and for making the effort to publish them on MathCity.org.
