Taming the Beast: Conquer Differential Calculus with Confidence (Part two)
In our first discussion on differential calculus, we introduced the notion of differentiability for a multivariate function ( f ). In this note, we explore the concept in greater depth. Let $$ f(x_1, dots, x_n) = f(mathbf{x}) $$ be a real-valued function defined on some open subset ( U subset mathbb{R}^n . Definition. The partial […]
