| 1. | It is popular to define the Riemann integral as the Darboux integral.
|
| 2. | The Riemann integral can only integrate functions on a bounded interval.
|
| 3. | If you use the Riemann integral, the answer is simply yes.
|
| 4. | A better route is to abandon the Riemann integral for the Lebesgue integral.
|
| 5. | As the shapes get smaller and smaller, the sum approaches the Riemann integral.
|
| 6. | The most commonly used definitions of integral are Riemann integrals and Lebesgue integrals.
|
| 7. | But this is a fact that is beyond the reach of the Riemann integral.
|
| 8. | There are some other technical difficulties with the Riemann integral.
|
| 9. | The Riemann integral uses the notion of length explicitly.
|
| 10. | The definition of a Banach-valued Riemann integral is an evident modification of the usual one.
