⁷ The formal statement of the Fundamental Theorem of Calculus is a little bit more complex than we have suggested. We omit detailed discussion of it here in order to stay true to our plan for a conceptual introduction, but the full explanation is, of course, widely available for those interested. Similarly, the actual details and methods for calculating integrals, especially integrals of tricky functions, are beyond what we intend to cover here—and in any event, can often be looked up in books like Gradshteyn and Ryzhik’s Table of Integrals, Series, and Products if you need them.
