👉 Regional calculus, or regional analysis, is a branch of mathematics that extends the principles of traditional calculus to functions defined on subsets of Euclidean space, such as regions in the plane or higher dimensions. It deals with studying how functions behave locally within these regions, focusing on properties like continuity, differentiability, and integrability. Unlike global calculus, which examines the behavior of functions over entire domains, regional calculus provides a more nuanced understanding by breaking down the function's behavior into smaller, manageable pieces defined by specific regions. This approach is particularly useful in applied mathematics and physics, where understanding local properties can be crucial for modeling real-world phenomena.
