Chapter 5  Applications of Derivatives"The derivative is supremely useful because there are so many ways to think of it. It is the instantaneous rate of change, enabling us to find velocity when position is given or acceleration when velocity is given. It also described sensitivity, how change in the input variable is reflected in the change of the output variable. And it has a geometric meaning, as the slope fo the tangent to the graph of a function. In this chapter, we will explore how all of these understandings of the derivative lead to applications."
