My lecturer posted a question asking why ""Real Analysis is all about infinity"
Why is this so?

Real analysis is a branch of mathematics that deals with the study of functions, sequences, and series of real numbers. It is the foundation of calculus and provides a rigorous framework for understanding and manipulating these mathematical concepts.
In real analysis, infinity is used as a concept to describe numbers that are infinitely large or infinitely small. This allows for the study of limits, which are essential for understanding the behavior of functions and sequences as they approach infinity or zero.
Real analysis is a more advanced and rigorous version of calculus. While calculus focuses on the manipulation of functions and their derivatives, real analysis delves deeper into the properties and behavior of these functions, including the use of concepts such as limits, continuity, and convergence.
Real analysis is important because it provides a rigorous and foundational understanding of calculus and other areas of mathematics. It also has practical applications in fields such as physics, engineering, and economics, where the behavior of functions and sequences is essential.
Real analysis can be challenging for some people due to its abstract nature and the use of advanced mathematical concepts. However, with dedication and practice, it is a subject that can be mastered. It is important to have a strong understanding of calculus and basic mathematical concepts before studying real analysis.
