Math 223 Calculus 3
LibreTexts
This book considers what happens when we broaden our view of what a function is to include functions that have more than one input, or that produce more than one result, or both. In particular, we consider what it means for such a function to have a limit, and how to differentiate or integrate such functions. In the course of learning these things, we will also encounter many applications of so-called multivariable and vector-valued functions in the natural and social sciences.
