Explain geometrically what the definition of the definite integral as a limit of Riemann sums represents. Include a labeled picture of a Riemann sum (for a particular $n$ ) that illustrates the roles of $n, \Delta x, x_{k}, x_{k}^{*},$ and $f\left(x_{k}^{*}\right) .$ What happens in the picture as $n \rightarrow \infty$ ?

(a) Give the definition of the definite integral as a limit. (b) State The Fundamental Theorem of Calculus Part 2. (c) Explain why using FTC 2 to compute integrals would be more practical (a lot less work).
