Calculus for Beginners and Artists

From Chapter 1 What is Calculus and Why do we Study it? “Calculus is the study of how things change. It provides a framework for modeling systems in which there is change, and a way to deduce the predictions of such models…It provides a way for us to construct relatively simple quantitative models of change, and to deduce their consequences.”
