Mathematical Analysis is a branch of mathematics that focuses on understanding the properties and behaviors of real and complex numbers. It involves studying concepts such as limits, continuity, derivatives, and integrals. These ideas help us analyze functions and their changes, making it essential for various fields, including physics and engineering. In Mathematical Analysis, we explore how functions behave as their inputs change. For example, we can determine how a small change in one variable affects another. This analysis is crucial for solving problems in calculus and helps us understand more complex topics like differential equations and real analysis.
