Calculus on Euclidean space

Calculus on Euclidean space refers to the extension of traditional calculus concepts, such as differentiation and integration, to higher dimensions in a Euclidean space \(\mathbb{R}^n\). In Euclidean space, we analyze functions of several variables, geometric shapes, and the relationships between them using the tools of differential and integral calculus. Key aspects of calculus on Euclidean space include: 1. **Multivariable Functions**: These are functions that take vectors as inputs.
