Chapter 6 - The Definite Integral"The need to calculate instantaneous rates of change led to the discoverers of calculus to an investigation of the slopes of tangent lines, and ultimately, to the derivative - to what we call differential calculus. In addition to a calculation method ( a "calculus") to describe how functions change at any given instant, they needed a method to describe how these instantaneous changes could accumulate over an interval to produce the function that describes the total change.
"Today, what we call the integral calculus or integration has two distinct interpretations. We begin this chapter by looking at integration as accumulation. But it also can be viewed as reversing the process of differentiation, what we call antidifferentiation. Newton's insight, that these two are connected, is what is called the Fundamental Theorem of Calculus." (Finney, Ross L., Franklin D. Demana, Bert K. Waits, and Daniel Kennedy. "Chapter 6."
