Please explain the solution (Real Analysis)

In summary, Real Analysis is a branch of mathematics that studies the properties of real numbers and the functions defined on them. It is important because it provides the foundation for calculus and has practical applications in various fields. The key concepts in Real Analysis include limits, continuity, differentiation, integration, sequences, and series, which are used to solve complex mathematical problems. It differs from other branches of mathematics by focusing on real numbers and using rigorous proofs. Real Analysis has many real-world applications in fields such as physics, economics, engineering, data analysis, statistics, and computer science.
