| 1. | Archimedes succeeded in summing what is now called a geometric series.
|
| 2. | The Neumann series, which is analogous to the geometric series
|
| 3. | It's how you simplify the geometric series, for instance.
|
| 4. | The same strategy works for any finite geometric series.
|
| 5. | Applying the formula for geometric series, we get
|
| 6. | This is a geometric series with common ratio 1 / ( 1 + I ).
|
| 7. | Then we reduce it to some form of geometric series and find the Laurent series.
|
| 8. | In that example we used the geometric series
|
| 9. | The geometric series model fits observed species abundances in highly uneven communities with low diversity.
|
| 10. | However, by summing a geometric series this expression can be expressed in the closed-form:
